Change Log

Workspace app and Receiver Versions

Workspace app is the new name for Receiver.

Upgrading Receiver to versions newer than 4.12 results in a new systray icon color (blue instead of black), and renaming from Receiver to Workspace app. Otherwise, functionality of Workspace app is identical to Receiver.

Workspace app changes the versioning to a YYMM (year/month) format, of which version 1810 is the newest. Version 1810 (or version 18.10) of Workspace app is an upgrade for Receiver 4.12 and Workspace app 1808.

LTSR (Long Term Service Release) versions of Receiver are still available, including version 4.9.4000 for XenApp/XenDesktop 7.15 LTSR, and version 4.4.5000 for XenApp/XenDesktop 7.6 LTSR.

Workspace app / Receiver Modules

The Workspace app / Receiver installer deploys multiple modules. Here are the important ones:

  • ICA Engine (wfica.exe) – process that uses the ICA protocol to connect to published apps and desktops.
  • Self-Service (selfservice.exe) – gets icons from StoreFront and displays them in a Window. When an icon is clicked, Self-service passes the ICA file to the ICA Engine to establish a connection.
  • Single Sign-on (SSON) for ICA (ssonsvr.exe) – captures user credentials and submits them to VDAs after an ICA connection is established
  • Workspace / Receiver Auto-Update (CitrixReceiverUpdater.exe) – Receiver 4.8 and newer – Notifies users of Receiver updates. The most recent name for this component is Citrix Workspace Update.

The PNAgent module is not included in Workspace app or Receiver 4.0 and newer. The older Receiver Enterprise includes the PNAgent module, but does not include Self-Service. The last version of Receiver Enterprise is 3.4.

Custom ICA files are no longer supported. However, Ryan Butler has created a script that asks StoreFront for an ICA file. Explicit credentials are supported. Find the script at Github.

Workspace app / Receiver Discovery and Beacon Process

If you are using Workspace app’s / Receiver’s built-in user interface (instead of a web browser), then Workspace app / Receiver first prompts you to perform discovery, which is also called Add Account.

Enter either a StoreFront FQDN, or a NetScaler Gateway FQDN. Just enter the FQDN. There’s no need to enter https or a path.

Workspace app / Receiver will contact the FQDN and request download of the StoreFront Provisioning File.

  • If you entered a StoreFront FQDN, then Workspace app / Receiver will download the Provisioning File directly from the StoreFront server.
  • If you entered a Gateway FQDN, then Gateway will first prompt the user to authenticate. After authentication, Gateway will connect to its configured Account Services address, and download the Provisioning File from StoreFront. The Account Services address is configured in the NetScaler Gateway Session Profile on the Published Applications tab.

If your StoreFront server is configured with multiple stores, then the user will be prompted to select a store. Unfortunately, there’s no configuration option in NetScaler Gateway to force a particular store.

The Provisioning File downloaded from StoreFront is an XML document containing values for several items configured in the StoreFront console. You can export the Provisioning File from the StoreFront console by right-clicking a Store.

The ReceiverConfig.cr Provisioning File looks something like this:

Here are the values in the Provisioning File:

  • Address – the Base URL configured in StoreFront Console
  • Internal Beacon – as configured in StoreFront Console. This can be the Base URL, or a manually specified URL.
  • External Beacons – as configured in StoreFront Console
  • Gateways – as configured in StoreFront Console. If there are multiple Gateways, when enabling Remote Access on the Store, then only one Gateway is selected as Default
  • SRID – Store ID. An important value to consider for multi-datacenter configurations. The SRID is set when the Store is created. It can also be changed by editing C:\inetpub\wwwroot\Citrix\Roaming\web.config.

Workspace app / Receiver reads the Provisioning File, and configures itself by inserting the file’s contents into the user’s registry. The values are located under HKCU\Software\Citrix\Dazzle\Sites and HKCU\Software\Citrix\Receiver\SR. If you performed discovery through NetScaler Gateway, notice that the internal Base URL is added to the user’s registry.

Once Workspace app / Receiver is configured, it then performs the following steps:

  1. Attempt to connect to the Internal Beacon.
  2. If the Internal Beacon is reachable, connect directly to the StoreFront Base URL (Address).
  3. If the Internal Beacon is not reachable:
    1. Attempt to connect to the External Beacons. If the External Beacons are not reachable, then stop attempting to connect.
    2. Connect to the Gateway address configured in the Provisioning File. If there is more than one Gateway, connect to the Gateway that is marked as the Default.

Here are some interesting notes on this connection process:

  • The FQDN you entered during Discovery has absolutely nothing to do with how Workspace app / Receiver connects to StoreFront or Gateway. The actual connection process is controlled by the contents of the Provisioning File, not the Discovery address.
  • If the Provisioning File has multiple Gateways defined, Workspace app / Receiver uses whichever Gateway is marked as Default. Workspace app / Receiver completely ignores whatever Gateway FQDN you entered during Discovery. To use a non-default Gateway, the user must manually select the other Gateway in Workspace app’s / Receiver’s Advanced Preferences.

In StoreFront Console, if any configuration changes are performed that affect the Provisioning File, do the Workspace apps / Receivers reconfigure themselves automatically? Or do users have to remove Accounts and re-add (or Reset Citrix Workspace / Receiver) so the updated Provisioning File is imported?

Here are some additional methods of performing Workspace app / Receiver Discovery:

  • After exporting the Provisioning File from StoreFront Console, distribute it to users, and ask them to double-click it.


  • After logging in to Receiver for Web (StoreFront), at the top right, click the user name, and click Activate. This downloads the receiverconfig.cr file, which is identical to the one you can export from StoreFront Console. The user then must run the downloaded file.

Uninstall Old Clients

Workspace app and Receiver 4.4 and newer includes Receiver Clean-Up, so, in theory, it’s not necessary to uninstall old clients first. For more details, see Citrix CTX135933 Upgrading to Citrix Receiver for Windows. To run it silently, run CitrixWorkspaceApp.exe /RCU /Silent or CitrixReceiver.exe /RCU /Silent 

For a reliable upgrade experience, write a script to remove the old clients, clean up the registry and file system, and then deploy the new Workspace app / Receiver.

Citrix Blog Post Cookbook to Upgrade from Receiver 3.4 for Windows to Receiver 4.2.100 and Citrix Article CTX135933 Upgrading to Citrix Receiver for Windows contains step-by-step procedure to use Group Policy to uninstall Receiver Enterprise 3.4 and install/configure Workspace app / Receiver 4.x.

The Receiver Clean-Up utility for Receiver 4.3 and older is designed to assist with the following scenarios:

  • When errors occur during upgrade from an earlier version of Receiver, or Online Plug-in
  • When unexpected behavior or performance is experienced after upgrade from an earlier Receiver or Online Plug-in
  • If Receiver upgrade is not possible due to feature incompatibility and/or a clean uninstall is required
  • The Receiver Clean-Up Utility removes components, files, and registry values of Online Plug-in 11.x, 12.x, and Receiver for Windows 3.x, 4.x (Online Plugin-in 13.x, 14.x). This includes the Offline Plug-in component if installed.

Installation and Configuration

This section contains a summary of all common command line switches, registry keys, and policy settings for Workspace app / Receiver.

Links:

CitrixWorkspaceApp.exe version 1810 (Current Release), or CitrixReceiver.exe version 4.9.4000 (Long Term Service Release), or CitrixReceiver.exe version 4.4.5000 (LTSR), can be installed by simply double-clicking it.


Administrator vs non-administrator

  • Non-administrator – If a non-administrator installs Workspace app / Receiver, then each non-administrator that logs in to the same workstation will have to reinstall Workspace app / Receiver.
    • Non-administrator installations are installed to %USERPROFILE%\AppData\Local\Citrix\ICA Client for each user.
  • Administrator – If CitrixWorkspaceApp.exe or CitrixReceiver.exe is installed using an administrator account. then the Workspace app / Receiver only needs to be installed once.
    • Administrator installations are installed to C:\Program Files (x86)\Citrix\ICA Client.
    • Administrator installations cannot be upgraded by non-administrators.
  • Conflicts – If an administrator install of Workspace app / Receiver is performed on a machine that has non-administrator installs of Workspace app / Receiver, then the two installations will conflict. Best option is to uninstall non-admin Workspace app / Receiver before installing admin Workspace app / Receiver. Otherwise, the user’s profile probably has to be reset before Workspace app / Receiver is functional again.

Receiver 4.12 Crypto Changes

Workspace app and Receiver for Windows 4.12 provide support for DTLS v1.2 for ICA connections to the VDA.

The latest Crypto Kit has deprecated all TLS_RSA_* cipher suites. For compatibility with VDA older than 7.18, there is an option in the Receiver GPO to enable/disable these cipher suites. Administrative Templates | Citrix Components | Citrix Workspace (or Receiver) | Network Routing | Deprecated Cipher Suites. More info at CTX234227 Receiver for Windows Crypto Kit Updates.

Some NetScaler configuration changes might be needed to handle the newer Crypto Kit. See CTX235241 Citrix Receiver for Windows– Troubleshooting Application or Desktop Launch Failures with TLS or DTLS

Auto-Update

Auto-Update is broken in Receiver 4.11 and older. You’ll have to manually install Workspace app 1810.

Workspace app / Receiver 4.8 and newer support auto-update. Some notes:

  • If Workspace app / Receiver is installed as administrator, then only administrators can install the auto-update.
  • If Workspace app / Receiver is installed on a VDA, auto-update is automatically disabled. This includes Remote PC.
  • Auto-update can be limited to LTSR updates only.
  • Auto-update is configurable through several mechanisms: group policy, StoreFront, Workspace app / Receiver GUI, installer command line. See Configuring Citrix Workspace Updates at Citrix Docs.

  • See George Spiers Citrix Receiver for Windows Auto-Update.

To troubleshoot Auto-update, see Citrix CTX226779 Troubleshooting Citrix Receiver Updates.

Auto-update is broken in Receiver for Windows 4.11 and older, and Receiver for Mac 12.9 and older. To fix it, manually upgrade to the next version (e.g. Receiver 12.9.1 for Mac), or install the Fix that can be downloaded from the Receiver download page (Source = CTX234657 Receiver Updater stops working with “Problem Checking for updates” error)

Auto-update is configured using Workspace app / Receiver group policy under the Citrix Workspace UpdatesReceiver Updates or Auto-Update node.




Workspace app Splash Screen

Workspace app shows a Splash Screen on first launch with the text “Citrix Workspace app extends the capabilities of Citrix Receiver”.

To prevent this splash screen, set the following registry value: (source = Dennis Span on Twitter)

  • Key = HKEY_CURRENT_USER\SOFTWARE\Citrix\Splashscreen
    • Value (REG_SZ) = SplashscreenShown = 1

Add Account Wizard

From Citrix CTX135438 How to Suppress the Add Account Window in Citrix Receiver for Windows: After installation, Workspace app / Receiver will launch and ask you to add an account. If Workspace app or Receiver 4.4.1000 or newer, notice the checkbox Do not show this window automatically at logon.

For Workspace app and Receiver 4.4 and newer, FTU (First Time Use aka Add Account Wizard) will be displayed only if a store is not configured. If a store is already configured via command line, GPO, or Citrix Studio, then FTU screen will not be available after installation. Otherwise, FTU can be suppressed by doing one of the following:  (Note: Receiver 4.4.1000 and newer has a fix for preventing the Add Account wizard)

  • Rename CitrixReceiver.exe to CitrixReceiverWeb.exe.
  • Rename CitrixWorkspaceApp.exe to CitrixWorkspaceAppWeb.exe.
  • Install using a command line switch:
    • CitrixWorkspaceApp.exe /ALLOWADDSTORE=N
    • CitrixReceiver.exe /ALLOWADDSTORE=N
  • Set the registry value: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Citrix\EnableFTU=dword:00000000 (or EnableX1FTU =dword:0)
  • Disable the EnableFTU policy setting in Receiver.admx.
  • Change Registry values post installation to suppress the Add Account window. Under HKLM\Software\Wow6432Node\Citrix\Dazzle, set AllowAddStore value to N.
  • Set the registry value: HKEY_LOCAL_MACHINE\Software\Citrix\Receiver\NeverShowConfigurationWizard (REG_SZ) = true
  • Also see Suppressing Add Account dialog at Citrix Docs.

Discover Hidden Stores

When Receiver is first launched, it must perform Discovery, which is the process of downloading the .xml provisioning file from StoreFront. Discovery is performed by entering a StoreFront FQDN or Gateway FQDN. To discover a hidden store (a store that’s not advertised), add %StoreName to the end of the FQDN. CTX214819 Unable to add account from Receiver dialog If the store is hidden in storefront.

Deploy Workspace app / Receiver using Active Directory

To deploy Workspace app / Receiver using Active Directory, configure a GPO with a computer startup script that runs the Workspace app / Receiver installer executable. Citrix has provided sample scripts that can be downloaded from one of the Workspace app or Receiver download pages (Workspace app version 1810 (Current Release), Receiver version 4.9.4000 (LTSR), or Receiver version 4.4.5000 (LTSR)) by expanding Downloads for Admins (Deployment Tools). An enhanced version of the installation script can be found in Citrix Discussions.

For Workspace app, you’ll have to edit the scripts and change CitrixReceiver.exe to CitrixWorkspaceApp.exe.

Also see CTA Dennis Span Citrix Receiver unattended installation with PowerShell.

Change Workspace App / Receiver Store Configuration, including Reset Citrix Workspace / Receiver

You can change Workspace app’s / Receiver’s configured Store/Account with a couple command lines: (from 4.4 LTSR store configuration per user at Citrix Discussions)

"C:\Program Files (x86)\Citrix\ICA Client\SelfServicePlugin\SelfService.exe" -deleteproviderbyname Corporate 
"C:\Program Files (x86)\Citrix\ICA Client\SelfServicePlugin\SelfService.exe" -init -createprovider Corporate https://storefront.corp.com/Citrix/Store/discovery

 

It is sometimes necessary to Reset Citrix Workspace or Reset Receiver by right-clicking the Workspace app / Receiver systray icon, clicking Advanced Preferences, and clicking the Reset link. You can do this from the command line by running "C:\Program Files (x86)\Citrix\ICA Client\SelfServicePlugin\CleanUp.exe" -cleanUser -silent. See CTX140149 How to Reset Receiver Using the Command Line.


Receiver for Edge

The Receiver for Web experience in Microsoft Edge is not ideal. Every time a user clicks an icon, the user has the click the Open button after the .ica file is downloaded.

Citrix Blog Post Providing Full Receiver for Web Experience for Microsoft Edge has instructions for enabling the Receiver Launcher for Edge. Use your preferred text editor to open web.config for the RfWeb site you would like to configure (typically C:\inetpub\wwwroot\Citrix\StoreWeb\web.config). Locate the line like this: <protocolHandler enabled="true" platforms="(Macintosh|Windows NT).*((Firefox/((5[3-9]|[6789][0-9])|\d\d\d))|(Chrome/((4[2-9]|[56789][0-9])|\d\d\d)))(?!.*Edge)". Remove (?!.*Edge) and save the file.

But once you do that, you get a new switch apps prompt every time you launch an icon from Edge.

To stop the switch apps pop-up, on the client side, edit the registry, go to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ProtocolExecute\receiver (create missing registry keys), create DWORD value WarnOnOpen, and set it to 0 (zero). You can use Group Policy Preferences to deploy this registry value.

Workspace app / Receiver Group Policy ADMX Template

Many of the Workspace app / Receiver configuration settings must be configured in group policy. These Workspace app / Receiver settings are only available after installing the GPO templates.

  1. From a machine that has Workspace app or Receiver installed, find the .admx and .adml files in the C:\Program Files (x86)\Citrix\ICA Client\Configuration.
    • You can also download the ADMX files from one of the Workspace app or Receiver download pages (Workspace app version 1810 (Current Release), Receiver version 4.9.4000 (LTSR), or Receiver version 4.4.5000 (LTSR)) by expanding Downloads for Admins (Deployment Tools).
  2. Copy the CitrixBase.admx and receiver.admx files. Also copy the en-US folder. In Workspace app, the files are still named receiver.admx.
  3. Go to your domain’s SYSVOL share and in the Policies folder look for a PolicyDefinitions folder. If one exists, paste the .admx file directly into the PolicyDefinitions folder. If this folder doesn’t exist in SYSVOL, instead copy the .admx file to C:\Windows\PolicyDefinitions. Overwrite any existing Receiver ADMX files.
  4. The GPO settings can then be found at one of the following:
    • Computer Configuration > Policies > Administrative Templates > Citrix Components > Citrix Workspace
    • Computer Configuration > Policies > Administrative Templates > Citrix Components > Citrix Receiver
  5. For example, you can disable Customer Experience Improvement Program (CEIP) from here.
  6. See https://www.carlstalhood.com/delivery-controller-7-18-ltsr-and-licensing/#ceip for additional places where CEIP is enabled.
  7. Workspace app 1808 and newer have User authenticationSingle Sign-on for NetScaler Gateway.
  8. Receiver 4.12 adds Network Routing | Deprecated cipher suites to configure deprecated ciphers.

  9. Citrix Workspace Updates, or Receiver Updates (aka AutoUpdate) can be configured using group policy. See Configuring Citrix Workspace Updates at Citrix Docs.


  10. Workspace app and Receiver 4.10 and newer have settings to hide Advanced Preferences, enable/disable DPI, and enable/disable H265.
  11. Workspace app and Receiver 4.8 and newer have SplitDevices GPO setting under Citrix Workspace | Remoting client devices | Generic USB Remoting. See Configuring composite USB device redirection at Citrix Docs.

  11. On the right, double-click Local user name and password.
  12. Select Enabled and then check the box next to Allow pass-through authentication for all ICA connections. Click OK.
  13. In Workspace app 1808 and newer, you can enable Single Sign-on for NetScaler Gateway.
  14. Ensure that the internal StoreFront FQDN is in the Local Intranet zone in Internet Explorer. You can use a GPO to configure this on the client side.
  15. Local Intranet zone should have Automatic logon only in Intranet zone enabled.
  16. Logoff Windows and log back on. In Task Manager you should now see ssonsvr.exe. This won’t appear unless you logoff and log back on.
  17. If Workspace app / Receiver won’t connect or is slow to enumerate icons, then you might have to disable Automatically detect settings in IE.
  18. In Receiver 4.5 and newer, right-click the Workspace app / Receiver icon and click Advanced Preferences.
  19. Click Configuration Checker.
  20. Check the box next to SSONChecker and click Run.
  21. The lines with red x will indicate the issue and corrective action.

StoreFront Accounts

You can use a client-side GPO to add a store (Account) to Workspace app / Receiver Self-Service.

  1. Install the receiver.admx (and .adml) template into PolicyDefinitions if you haven’t already.
  2. Edit a GPO that applies to endpoint devices that have Citrix Workspace app or Receiver installed.
  3. Go to Computer Configuration > Administrative Templates > Policies > Citrix Components > Citrix Workspace (or Receiver) > StoreFront.
  4. On the right, double-click NetScaler Gateway URL/StoreFront Accounts List.
  5. Select Enabled, and then click Show.
  6. Enter a store path based on the example shown in the Help box. Workspace app and Receiver 4.5 let you enter a Gateway path. Then click OK.
  7. Note: Gateway paths work in GPO, but might not work when specified in the CitrixReceiver.exe installation command line.

Published Shortcuts and Reconnect

Citrix CTX200924 How to Customize App Shortcuts with Receiver for Windows

Workspace app and Receiver 4.5 and newer have a user interface for setting Shortcut Paths. Right-click the Workspace app or Receiver systray icon, click Advanced Preferences, and then click Shortcuts and Reconnect, or Settings Option.


From Citrix Docs Configuring application delivery: There are several methods of controlling how Workspace app / Receiver displays shortcuts on the Start Menu and Desktop as detailed below:

Under HKLM\Software\Wow6432Node\Citrix\Dazzle (or HKCU\Software\Wow6432Node\Citrix\Dazzle) are several registry values related to shortcuts. Some of the settings only apply if SelfServiceMode is set to False. Here are some common options:

  • SelfServiceMode – set to False so Receiver disables the Self-Service interface and automatically places all published shortcuts on the Start Menu and/or Desktop. More details in Configuring application delivery at Citrix Docs.
  • PutShortcutsOnDesktop – set to True to place every app on the desktop
  • DesktopDir – Workspace app / Receiver places every shortcut on the desktop so it’s probably best to place them in a folder.
  • StartMenuDir – If there is potentially a conflict between local apps and remote apps, then you should place the Start Menu shortcuts in a folder.
  • PreferTemplateDirectory (with KEYWORDS:prefer=shortcutname) – copies the shortcutname from the template directory to the Start Menu and/or Desktop.

If you import the receiver.admx (and .adml) into the PolicyDefinitions folder, under Computer Configuration > Administrative Templates > Citrix Components > Citrix Workspace (or Receiver) is a node called SelfService.

Disable the Manage SelfServiceMode setting to hide the Workspace app / Receiver Window.

Enable the Manage App shortcut setting to control placement of shortcuts.

Workspace app and Receiver 4.2.100 and newer have the ability to configure (or disable) Workspace Control using group policy. Enable the setting Control when Citrix Workspace attempts to reconnect to existing sessions and configure it as desired.

Prelaunch

Staring with Receiver 4.2, prelaunch is automatically enabled if Workspace app / Receiver is installed with SSON enabled. Otherwise, set registry values to enable prelaunch. Receiver 4.2.100 prevents the prelaunch icon from appearing on the Start Menu.

  • HKLM\Software\[Wow6432Node\]Citrix\Dazzle
    • EnablePreLaunch (REG_SZ) = true or false

Additional customizations can be configured at:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client\Prelaunch

  • Name: State
    • REG_SZ: 0 = disable, 1 = just-in-time pre-launch, 2 = scheduled pre-launch
  • Name: Schedule
    • REG_SZ: HH:MM|M:T:W:TH:F:S:SU where HH and MM are hours and minutes. M:T:W:TH:F:S:SU are the days of the week. For example, to enable scheduled pre-launch on Monday, Wednesday, and Friday at 1:45 p.m., set Schedule as Schedule=13:45|1:0:1:0:1:0:0 . The session actually launches between 1:15 p.m. and 1:45 p.m.
  • Name: UserOverride
    • REG_SZ: 0  = HKLM overrides HKCU, 1 = HKCU overrides HKLM

Device Access Behavior (Client Selective Trust)

When connecting to a XenApp/XenDesktop session, you might see the following:

To configure the default behavior, see the Citrix Knowledgebase article How to Configure Default Device Access Behavior of Receiver, XenDesktop and XenApp. Note: there is a bug fixed in Receiver 4.2.100 and newer.

  1. Download the ADMX file from http://support.citrix.com/article/CTX133565.
  2. Copy the .admx and .adml files to PolicyDefinitions (Sysvol, or C:\Windows).
  3. The .adml file goes in the en-US folder.
  4. Edit a GPO that applies to the endpoint devices that are running Receiver.
  5. Go to Computer Configuration | Policies | Administrative Templates | Citrix Components | Citrix Workspace (or Receiver) |  Citrix Client Selective Trust (x64).
  6. Enable the setting Create Client Selective Trust Keys.

  7. Then expand the regions, and configure the permission settings as desired.

Desktop Lock

As an alternative to Workspace app / Receiver Desktop Lock, see Transformer in Citrix Workspace Environment Manager.

External links:

Use Studio to configure Workspace app / Receiver Accounts in Published Desktop

In published desktops, Workspace app / Receiver can be used for placement of shortcuts on the user’s Start Menu and Desktop. Use group policy to hide the common program groups and then use Workspace app / Receiver to place published applications back on the Start Menu and Desktop based on user’s group membership and subscription preference.

  1. In Citrix Studio, on the left, expand the Configuration node, right-click StoreFront and click Add StoreFront.
  2. Enter a descriptive name for the StoreFront server.
  3. Enter the internal https URL of the load balanced StoreFront servers. Add the path to your store (e.g. /Citrix/Store) and then /discovery on the end of the URL. The full URL would be similar to https://citrix.corp.com/Citrix/Store/discovery. Click OK.
  4. Edit a Delivery Group that has a published desktop and Citrix Workspace app / Receiver installed.
  5. On the StoreFront page, change the selection to Automatically, using the StoreFront servers selected below, and then check the box next to the StoreFront URL. Click OK. Now when users launch the published desktop, Workspace app / Receiver will be automatically configured with this URL.

Published Desktop – use Workspace app / Receiver to control Shortcuts

If you install Workspace app / Receiver inside a published desktop (Workspace app / Receiver on a VDA), then Workspace app / Receiver can get icons from StoreFront and put those icons on the user’s published desktop Start Menu and Desktop. This is an alternative to using a User Experience Management product to control shortcut placement.

Note: Workspace app / Receiver tends to be slow to create Start Menu shortcuts, so make sure you perform a Proof of Concept to determine how this functionality impacts logon times.

Configuration of Workspace app / Receiver inside a published desktop is simplified if you have the following minimum versions:

  • Workspace app or Receiver 4.11 or newer installed inside the VDA
  • VDA 7.17 or newer
  • StoreFront 3.14 or newer

If you meet these minimum version requirements, then Workspace app / Receiver installed in the VDA automatically tries to launch published applications on the same local VDA rather than trying to launch them from a different VDA (aka double-hop). This feature is called vPrefer.

Do the following for all versions of Workspace app / Receiver, VDA, and StoreFront, whether using the Prefer keyword or not:

  1. Make sure Workspace app or Receiver version 4.11 or newer is installed on the VDA. Or install Receiver version 4.9.4000 (LTSR), or version 4.4.5000 (LTSR)
  2. Install the Workspace app / Receiver ADMX files if you haven’t already. For vPrefer, make sure they are the ADMX files from Workspace app or Receiver 4.11 or newer.
  3. Enable the Group Policy setting Remove common program groups from Start Menu and apply it to non-administrators.
    • This removes all Public (aka All Users) Start Menu shortcuts. Workspace app / Receiver will re-add the shortcuts based on user group membership.
  4. On the VDA, configure the following Workspace app / Receiver Registry keys (or corresponding settings in the receiver.admx GPO template):
    • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle\WSCReconnectMode=”0″ so Workspace app / Receiver doesn’t try to reconnect to the published desktop you’re already running.
    • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle\SelfServiceMode to False. This turns off the Workspace app / Receiver Self-Service GUI and acts like all icons are subscribed. Otherwise, only subscribed (favorited) icons would be placed on the Start Menu and Desktop.
    • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle\UseCategoryAsStartMenuPath = True. This creates a Start Menu folder based on the published app’s configured Category.
  5. Configure each desired published app to Add shortcut to user’s desktop.

    • Or, configure HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle\PutShortcutsOnDesktop = True to place all icons on the desktop.
  6. To control icon placement, configure the following registry values:
    • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle\StartMenuDir to place published applications in a sub-folder. Note: Windows 2012 and newer only supports a single level of Start Menu folders, so setting this effectively turns off published app categories.
    • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle\DesktopDir to place published applications in a sub-folder on the desktop.
  7. Pass-through authentication:
    1. In a GPO that applies to the VDA, import the receiver.admx file, and set Local user name and password to Enabled. Check the box next to Allow pass-through authentication for all ICA connections.
    2. If you’re using Gateway internally, and if Workspace app 1808 or newer, then also enable Single Sign-on for NetScaler Gateway.
    3. In a user-level GPO that applies to the VDA, add the StoreFront FQDN to the Local Intranet zone. Make sure it is not in the Trusted Sites zone, or enable Automatic logon with current user name and password for the Trusted Sites zone.
    4. Make sure ssonsvr.exe is running after you login to the VDA. If not, troubleshoot it.
  8. When configuring Citrix Profile Management, make sure !ctx_startmenu! is not excluded from roaming.
  9. In Citrix Studio, configure a Delivery Group with delivery type = Desktop and Applications. Assign users to the delivery group, and the individual published applications (if visibility is limited).
    1. In Citrix Studio, edit each published application, and on the Delivery tab, specify a category. This will become the Start Menu folder name.
    2. If Workspace app / Receiver Self Service Mode (GUI) is enabled, in Studio, edit each application, and add KEYWORDS:Auto and/or KEYWORDS:Mandatory to the published application description. This forces the applications to be subscribed/favorited. Only subscribed (or Favorite) apps are displayed in the Start Menu and Desktop. Unless you disable Workspace app / Receiver’s SelfService interface as described earlier.
    3. Another option is to go to the StoreFront Console, click Stores on the left, and on the right, click Configure Store Settings, and click Disable User Subscriptions. This causes all apps to appear on the Start Menu and/or Desktop depending on Workspace app / Receiver configuration.
  10. Create a group policy that applies to VDAs, and configure the group policy to define the Store URL for Workspace app / Receiver similar to https://citrix.corp.com/Citrix/Store/discovery. Replace the FQDN with your load balanced StoreFront FQDN. Also replace the path to the store with your store path. Make sure there is /discovery on the end. By default, Workspace app / Receiver only supports https.
    1. Your StoreFront store probably delivers both application and desktop icons. If you want to filter out the desktop icons, then create a new StoreFront store, and configure the Workspace app / Receiver on the VDA to connect to the new Store.
    2. In StoreFront Console, click the store for VDAs, and click Configure Store Settings. On the Advanced Settings page, in the Filter resources by type row, choose Citrix.MPS.Desktop.
  11. For vPrefer in Workspace app or Receiver 4.11 (or newer), VDA 7.17 (or newer), and StoreFront 3.14 (or newer), edit a GPO that applies to the VDAs.
    1. Go to Computer Configuration | Policies | Administrative Templates | Citrix Components | Citrix Workspace (or Receiver) | SelfService.
    2. Edit the setting vPrefer. This setting is only in Workspace app / Receiver ADMX templates from Workspace app / Receiver 4.11 and newer.
    3. Set it to Allow all apps. Source = 7.17 vPrefer – not working with 32Bit Apps at Citrix Discussions.
  12. On your Delivery Controller, in PowerShell, run set-brokersite -TrustRequestsSentToTheXmlServicePort $true
    • This is required for Pass-through Authentication from Workspace app / Receiver.
  13. Configure your client devices to connect to the published desktop.
    1. When users connect to the published desktop, Workspace app / Receiver will auto-launch and hopefully auto-login.
    2. If Workspace app / Receiver Self-Service Mode is disabled, all published applications should automatically appear in the Start Menu and Desktop.
    3. If Workspace app / Receiver Self-Service Mode is enabled, then only applications with KEYWORDS:Auto and/or KEYWORDS:Mandatory in the published application description will be displayed. Users can open the systray icon to subscribe to more applications.
    4. Users can copy icons from the Start Menu to the desktop. Make sure the user Copies the icon and doesn’t Move it.
    5. Users can then launch applications directly from the Start Menu, from the Desktop, or from the Workspace app / Receiver (if the Self-Service interface is enabled).
    6. If Workspace app or Receiver 4.11 (or newer), VDA 7.17 (or newer), and StoreFront 3.14 (or newer), then vPrefer is enabled by default. When launching an app icon that came from Workspace app / Receiver, Workspace app / Receiver checks the local VDA machine to see if the application can be launched on the local VDA instead of by creating a new Citrix double-hop session.
    7. If the application is installed locally on the VDA then the local application shortcut should launch quickly. If the application is on a different delivery group then a second (double-hop) Citrix HDX/ICA connection will be established.
    8. If the user deletes Workspace app / Receiver shortcuts from the Start Menu, you can get them back by going to the systray icon and refreshing the applications. Or sometimes you have to reset Workspace app / Receiver.

If you are running components older than Receiver 4.11, VDA 7.17, and StoreFront 3.14, then you’ll need to configure the prefer keyword to get Receiver delivered icons to launch on the local VDA instead of in a new double-hop Citrix connection.

  1. Enable the Group Policy setting Remove common program groups from Start Menu and apply it to non-administrators.
    1. For applications that are installed on the same VDA that is publishing the desktop, configure Group Policy Preferences to recreate the application shortcuts based on Active Directory group membership. Applications on other delivery groups are handled by Receiver.
    2. Or use the prefer keyword to copy shortcuts from the PreferTemplateDirectory.
  2. On the VDA, configure the following Receiver Registry keys (or corresponding settings in the receiver.admx GPO template):
    • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle\PreferTemplateDirectory = a UNC path or local path containing shortcuts to be copied by the prefer keyword. This can point to C:\ProgramData\Microsoft\Windows\Start Menu.
  3. In Citrix Studio, configure a Delivery Group with delivery type = Desktop and Applications. Assign users to the Delivery Group and the applications (if visibility is limited).
    1. In Studio, edit each application and change KEYWORDS:Prefer to KEYWORDS:prefer. Notice the lower case p. It doesn’t work with uppercase P.
      • With the prefer keyword, if you publish an application that is also created using Group Policy Preferences, the Group Policy Preferences icon will take precedence. This is good. Otherwise the Receiver published application icon would result in a new Citrix double-hop session.
      • See Ralph Jansen Citrix Receiver 4.1 Prefer keyword examples
    2. If using the prefer keyword with the PreferTemplateDirectory, enter it as KEYWORDS:prefer=shortcutname where shortcutname is the name of the shortcut that is copied from the Template directory.
  4. Configure your client devices to connect to the published desktop.
    1. When users connect to the published desktop, Group Policy Preferences will create shortcuts to local applications.
    2. Receiver will auto-launch and hopefully auto-login.
    3. If Receiver Self-Service Mode is disabled, all published applications should automatically appear in the Start Menu and Desktop.
    4. If Receiver Self-Service Mode is enabled then only applications with KEYWORDS:Auto and/or KEYWORDS:Mandatory in the published application description will be displayed. Users can open the systray icon to subscribe to more applications.
    5. For published applications with KEYWORDS:prefer=shortcutname, Receiver should copy icons from the template directory to the Start Menu and/or Desktop. See below for considerations.
    6. Users can copy icons from the Start Menu to the desktop. Make sure the user Copies the icon and doesn’t Move it.
    7. Users can then launch applications directly from the Start Menu, from the Desktop, or from the Receiver (if Self-Service interface is enabled).
    8. If a local shortcut (e.g. Group Policy Preferences shortcut, or copied from template directory) matches a published application with KEYWORDS:prefer then the local shortcut will override the published application icon.
    9. If the application is installed locally on the VDA then the local application shortcut should launch quickly. If the application is on a different delivery group then a second (double-hop) Citrix HDX/ICA connection will be established.
    10. If the user deletes Receiver shortcuts from the Start Menu, you can get them back by going to the systray icon and refreshing the applications. Or sometimes you have to reset Receiver.

Notes regarding Prefer Template Directory

  • Prefer Template Directory can point to C:\ProgramData\Microsoft\Windows\Start Menu, which is the All Users Start Menu.
  • The shortcuts copied from the Prefer Template Directory are renamed to match the published app name.
  • For prefer local apps, any command line parameters specified in the published app are ignored. If you need these command line parameters, add them to the shortcut in the Prefer Template Directory.
  • If you have multiple published apps pointing to the same prefer local shortcut, then only one copy will be made, and it will have the name of only one of the published apps. To workaround this, in the Prefer Template Directory, create separate shortcuts for each published app, and adjust the published app prefer keyword accordingly.
  • Jan Hendrik Meier Automatic Shortcut generation for local installed applications in a Citrix XenDesktop / XenApp 7.x environment has a script that can create shortcuts based on the published apps with prefer keyword. These shortcuts can then be copied to your Prefer Template Directory.

How to Script Workspace app / Receiver Self-Service

From Citrix Knowledgebase article Driving the Citrix Receiver Self-Service Plug-in Programmatically: by default, Workspace app / Receiver Self-Service (SSP) activities are driven by user interaction. However, SSP exposes sufficient information for its activities to be scripted.

When SSP builds a shortcut, it builds it to a small stub application in a file %appdata%\Citrix\SelfService\app-name-with-spaces-removed.exe for each resource. These files allow SSP to create a fake ‘install’ record for Add/Remove Software. Running these .exe files causes the application to launch. Note: Workspace app and Receiver 4.3.100 and newer don’t create stubs by default. To enable, set HKLM\Software\Wow6432Node\Citrix\Dazzle\AlwaysUseStubs (REG_SZ) = true.

If you want to drive SSP directly for launch instead of through an .exe stub, look at the keys under HKCU\Software\Microsoft\Windows\CurrentVersion\Uninstall. There will be keys in there named farm-name@@server-farm-name.app-friendly-name. In these keys you’ll find a LaunchString value that shows the relevant parameters. These parameters are user-independent and can therefore be cloned from a reference user to a general case. You can copy and reuse these parameters without interpretation.

Running the command selfservice.exe –init –ipoll –exit starts SSP, performs a refresh (interactive poll) from the current provider, and forces a clean exit.

Additional command line parameters are detailed at Driving the Citrix Receiver Self-Service Plug-in Programmatically.

 

Citrix Workspace app / Receiver comes with a .dll file that implements the Citrix Common Connection Manager SDK. You can use the CCM SDK to do the following:

  • Launch Sessions
  • Disconnect Sessions
  • Logoff Sessions
  • Get Session Information

Citrix was kind enough to develop a PowerShell module that calls functions from the .dll. Get the CCMPowershellModule from Github. The PowerShell module contains functions like the following:

  • CCMTerminateApplication
  • CCMLaunchApplication
  • CCMGetActiveSessionCount
  • CCMDisconnectAllSessions

Launcher Scripts

Stan Czerno – Powershell Script to launch one or more Published Applications from Citrix Storefront 2.x through 3.6: the script launches a browser, connects to StoreFront (or NetScaler Gateway), logs in, and launches an icon. This is a very well-written script that uses a .dll file from Citrix Workspace app / Receiver to display session information.

Citrix Solutions Lab StoreFront Launcher Script at Github. It attempts to closely resemble what an actual user would do by:

  1. Opening Internet Explorer.
  2. Navigating directly to the Receiver for Web site or NetScaler Gateway portal.
  3. Completing the fields.
  4. Logging in.
  5. Clicking on the resource.
  6. Logging off the StoreFront site.

Skype for Business

Citrix has a HDX RealTime Optimization Pack for Workspace app / Receiver that enables offloading of Skype for Business media protocols to the client device. Here are the available versions:

The HDX RealTime Optimization Pack comes in two pieces: the Connector (on the VDA), and the Media Engine (on the Workspace app / Receiver machine). Usually both pieces must be the same version, but versions 2.3 and higher now allow version mixing.

24-page Citrix PDF Delivering Microsoft Skype for Business to XenApp and XenDesktop Users.

For Skype for Business Location Based Routing, you’ll need the following: (Source = Citrix Derek Thorslund at Location based routing at Citrix Discussions)

  • Microsoft added support for Location Based Routing (LBR) with the virtualized Skype for Business 2016 client (and HDX RTOP 2.1 and above) in the Click-to-Run (C2R) download quite a long time ago, but it hasn’t yet been introduced in the MSI package.
  • It requires setting IsLBRInVDIEnabled on the Skype for Business Server to True:
    $x = New-CsClientPolicyEntry -Name "IsLBRInVDIEnabled" -Value "true"
    Set-CsClientPolicy -Identity "<ClientPolicyName>” -PolicyEntry @{Add=$x}

When offloading voice and video to Workspace app / Receiver machines, don’t forget to configure QoS on the client machines. See Citrix Blog Post Implementing the Citrix HDX RealTime Optimization Pack: Don’t Forget About QoS/DSCP.

Citrix CTX222459 RealTime Optimization Pack Capability Checker: It will list out endpoint hardware/software information which will be used to process audio and video. The tool is independent of RealTime Optimization Pack version and runs any Windows machine.

Citrix CTX214237 LOPper – Lync Optimization Pack Log Parser: parses log files generated by Citrix HDX RealTime Optimization Pack (HROP) when an audio/video call is made using Lync 2013/Skype for Business (SfB) and shows relevant information in a UI.

Troubleshooting – Citrix QuickLaunch

Citrix CTX219718 QuickLaunch Tool (Testing Application and Desktop Launch) lets you launch Citrix sessions directly from a Controller without needing StoreFront.

You enter a Controller address, credentials, and then it shows you the published resources. You can pick a resource, edit properties on the other tabs, and then Connect. This allows you to easily try different connection properties.

If you run into problems launching a session, use Sysinternals DebugView while running CQL in Debug mode (/debug switch).

Troubleshooting – Workspace app / Receiver Logging

There are a couple methods of logging Workspace app / Receiver for Windows operations. One method is CTX141751 Citrix Receiver Diagnostics Tool – For Windows, which creates a CDF trace that can be parsed by CDFControl.

Another method is CTX132883 How to Enable Logging on Receiver for Windows Using Registry Entries. The logfiles in %USERPROFILE%\Appdata\Local\Citrix\ are human readable. And CTX206102 Enable SSON Logging Using Registry Key.

Instead of creating the registry keys manually,  you can use the following .reg file provided by Wolfgang Thürr:

Windows Registry Editor Version 5.00

Troubleshooting – Duplicate Stores

Stores are sometimes duplicated in Workspace app / Receiver, especially if you are running Workspace app / Receiver inside a VDA. (h/t Dan High)

StoreFront URLs can be defined in several places:

  1. In Studio, go to Configuration > StoreFront and delete all URLs configured here.
  2. Look in GPOs for Computer Configuration > Administrative Templates > Policies > Citrix Components > Citrix Workspace (or Receiver) > StoreFront > NetScaler Gateway URL/StoreFront Accounts List. Remove any URLs configured here.
  3. In the client-side registry, at HKLM\Software\Wow6432Node\Citrix\Dazzle\Sites, you might see store addresses that were specified during a command line installation of Workspace app / Receiver.
  4. When Citrix Workspace app / Receiver switches between StoreFront servers in multiple datacenters, it’s possible for each datacenter to be treated as a separate Workspace app / Receiver site. This can be prevented by doing the following. From Juan Zevallos at Citrix Discussions:
    1. Match the BaseURL in all datacenters.
    2. Match the SRID in all datacenters – The SRID can be safely edited in the C:\inetpub\wwwroot\Citrix\Roaming\web.config. Make sure to propagate changes to other servers in the group.
    3. Match the Delivery Controller names under “Manage Delivery Controllers” – The XML brokers can be different, but the actual name of the Delivery Controller/Farm must be identical. Here’s the exact setting I’m referring to: https://citrix.sharefile.com/d/sa562ba140be4462b

If you are running Workspace app / Receiver on a VDA, once you’ve removed the configured URLs shown above, do the following to clean up the VDAs:

  1. On the VDA, HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Citrix – Delete the number folders representing policy entries.
  2. On session host VDAs, HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Terminal Server\Install\Software\Citrix – Remove the entries for storefront in the following folders.
    1. Under \receiver\ctxaccount delete all entries.
    2. Under \SR\Store delete the entries.
  3. On the VDA, C:\ProgramData\CitrixCseCache – Delete all files
  4. On the VDA, C:\ProgramData\Citrix\GroupPolicy – Delete all folders and files.
  5. Run gpupdate and logoff.
  6. In the user’s registry, HKEY_CURRENT_USER or the profile registry hive. Possible profile reset.
    1. Under Software\Citrix\Dazzle\Sites – Delete all entries.
    2. Under Software\Citrix\Receiver\ctxaccount – delete all entries.
    3. Under Software\Citrix\SR\Store – delete the entries.
  7. Verify no cached profile folders for user on server.

  1. Hi Carl, any idea on how to suppress the Workspace App FTU on a Mac? All articles seem to point to Windows client only.

    1. If you rename the installer to CitrixWorkspaceAppWeb.dmg then it will not show similar to how installation via RfWeb happens.

  2. Hi All !
    I would like to use Receiver Desktop Lock in our environment. As for now we’re using 4.9 CU3 (LTSR), should I use the same level of Desktop Lock or it doesn’t matter as there is no LTSR branch (if I’m not wrong) ?
    Thanks for your advice

      1. Thanks for the reply,

        I saw that there is a Desktop Lock (DL) for each version of Citrix Receiver
        My question was more about to know if I have to respect versions R 4.9 / DL 4.9 or DL can be superior to R

  3. Hello, thank you for everything. I need your advice … We can not configure (but is it possible?) Citrix Workspace App, with as an entry in the “account” field, the alias (alias.mydomain.com) of the address of our Netscaler Gateway instead of the normal address (netscaler.mydomain.com). Do you have any leads to give us?

      1. Yes all work fine with the Gateway FQDN but when we enter the alias FQDN it doens’t work. We try with the alias because the adress is more complicate for our users: the fqdn of the netscaler is netscaler-gateway.domain.com, and we create an alias in our dns ok.domain.com for having an more simple adress. When our customers are not in our place, they can use an internet browser with the adress ok.domain.com and all is ok. We try to enter ok.domain.com in Citrix Workspace App and it doesn’t work, but, when we enter netscaler-gateway.domain.com, it works. is it possible to make it work with ok.domain.com ?(sorry for my bad english, i hope you understand what i mean, and thank you for your responses)

  4. Hi Carl

    I have two questions regarding an issue with beacon / location detection we have with the Workspace Client for Mac. We have the issue that sometimes the Workspace Client for Mac tries to reach the – unreachable – internal beacon from outside our network for 80 seconds while ignoring the – reachable – external beacons which results in a 80s wait time for the user until he can connect. We do not need the check because all our users connect from the outside (external) through a netscaler gateway to the storefront server – there is no “internal” connection possible…

    1. Where are the settings stored on a Mac which are part of the registry on a Windows client and how can they be changed (if not available through the app itself)?
    2. Is there a way to disable the whole location checking (internal/external) that the Workspace Client always performs after a network adapter change.

    Extract from the ServiceRecord.log client logfile:

    [2018-10-11 09:22:05.046] [T0Unknown] [ServiceRecordMain.mm:157] BeaconDetector Routing table changed: Internal ras-storefront.vt.ch expect arrival within 80.000 seconds
    [2018-10-11 09:22:05.046] [T0Unknown] [ServiceRecordMain.mm:157] -[BeaconDetector nextCheckID] Internal ras-storefront.vt.ch(540) Connection (0) Start checking
    [2018-10-11 09:22:05.046] [T0Unknown] [ServiceRecordMain.mm:157] BeaconDetector Routing table changed: Ignoring External myras.vontobel.com
    [2018-10-11 09:22:05.046] [T0Unknown] [ServiceRecordMain.mm:157] BeaconDetector Routing table changed: Ignoring External ping.citrix.com

    Every idea to solve this issue would be very much appreciated (the funny thing is that with the Workspace Client for Windows we do not have the issue)…

    Regards, Dieter.

  5. Seeing something weird in our environment. 7.15 CU2 VDA on Win10, uninstall Workspace App from the VDA and it removes the Citrix Display Only Adapter and now you can no longer connect to the VDA. The only way I found to fix it is reinstall the Citrix VDA.

  6. Hi Carl,

    at the moment I use the Netscaler with otp purely over the web, is it now also possible to get an authentication with the new Workspace App ?
    When configuring the Workspace App, it offers me a username / password and passcode, after entering it, unfortunately the login is forbidden.

    So I ask myself if the Workspace App supports OTP logins or not?

    Thank you and greetings
    Thomas

    1. I think native OTP is based on nFactor, which I don’t think is supported in Workspace App, yet. nFactor support was recently added to Gateway VPN Plug-in.

  7. Hi all!
    The last few days we have seen an increasing number of users not being able to connect to Xenapp desktop via Storefront.
    What we have seen on all affected clients,
    Receiver is ver. 4.9
    HDX plugin 2.4 is installed
    Security update to Flash player has resently been installed KB4343902.

    What we also see in event log is this:

    Product: Citrix HDX RealTime Media Engine 2.4 — Error 1706. An installation package for the product Citrix HDX RealTime Media Engine 2.4 cannot be found. Try the installation again using a valid copy of the installation package ‘HDX_RealTime_Media_Engine_2.4_for_Windows.msi’.

    We fixed It by uninstalling HDX plugin and receiver, and then running “clean up” tool > reboot pc
    Then reinstalling receiver and hdx plugin

    Do any of you guys have experienced this issue?

    Btw. Are HDX plugin integrated in new Workspace client, or Is it still an separate component?

  8. some great articles here btw.
    We have issue with one of our Applications when launch using Publish App, user cannot enter the password as they cant see any text they are typing in password field. This issue seem to happen to mobile devices. any ideas

  9. G’day Carl, I’ve got a problem with Receiver 4.10 and 4.10.1 where if a user does a ‘Send to Desktop’ on an app published to a start menu folder, the resultant icon is removed when the receiver is refreshed. This behavior doesn’t occur in 4.9 and before however. Any ideas?

    1. Just following up re: this. The shortcuts disappear when the user accesses a Citrix application, and this behavior does occur with Receiver 4.9, but only when clean installed. If I installed 4.6, logged in to the Receiver, and then installed 4.9 over the top, the icons would remain. Trying this same method with 4.10 and 4.10.1 didn’t work. Receiver 4.6 has no problems at all.

      1. Hello Stefan, Sorry for the late reply. We had a similar problem. The icon you use for the published application is the problem. It needs to include the following sizes (in px): 16×16, 32×32, 48×48 at a minimum. To accommodate for high dpi devices we also add 128×128, 256×265 and 512×512. Many times even the vendors have only one size for an application icon, which is just laziness, but causes this issue for us. I use icofx3 to merge all the sizes into a single .ico file. We have reported this issue to Citrix in 2017. I believe Citrix Receiver v4.11 might have fixed this issue though?

  10. Hi Carl,
    Does Local App Access integrate with Citrix Desktop Lock ? I am able to get LAA and Desktop Lock work separately but not together. Is there something I am doing wrong or is it by design? Thank you for anticipated answer, I just have a client requirement to allow LAA into win7 with Desktop lock installed for their 6.5 environment.
    Cheers

  11. Carl,
    Just ran into an issue with 4.10.0.16036, it appears to break access to Legacy Xenapp 5 Servers. Was wondering if you have heard or ran into this issue. (Yes I know this has been EOL since 2013)

  12. Anyone had first hand experience of this fixing the authentication popup box which appears randomly. Citrix support have reported it does, don’t want to waste my time testing as I have multiple SDP’s to work on. Thanks.

  13. We have exactly the same problem in our published apps. Combo boxes drop down their list but nothing happens when you click on them while using Receiver 4.10. This is a critical problem for us. We are advising our customers to roll back to Receiver 4.9 but some of them have been receiving automatic updates and are not technically minded enough to handle the rollback well.

  14. Hello Carl,

    We have found a bug in 4.10.

    Office 2010 document with dropdown select boxes.
    Clicking on the box opens the dropdown list but clicking on an item does nothing. You can highlight an item then press “Enter” on the keyboard.

    I’m having to rollback to 4.9 as this is not an issue there. I don’t know what other application will be affected by this issue.
