Citrix Workspace app for Windows 2503.10 Technology Preview available for testing. Long list of fixed issues: • You might get a “LaunchBox Com Error: Class not registered” pop-up message when opening a virtual desktop using CyberARK. [CVADHELP-28177] • Citrix Workspace app might block Dell Optimizer from monitoring registry values. [CVADHELP-28035] • The Zoom or Webex plug-in might not install during store addition when Citrix Workspace app is configured for installation using GACS. [CVADHELP-28298] • When an admin installs Citrix Workspace app on a machine where a user has already installed it, the user’s Citrix Workspace app shortcut and any published app or desktop shortcuts remain on the system. [CVADHELP-27513] • On Azure AD joined machines, signing in to Citrix Workspace app might fail when the user name is specified in UPN format. [CVADHELP-27968] • You might notice that Citrix Workspace app keeps spinning when opening the application. This issue occurs if the account configuration is incomplete and the AuthManLiteSupport registry is set to false. [CVADHELP-28073] • When App Protection service is running, some Windows startup services might crash or fail to start due to compatibility issues. This issue affects Citrix Workspace app for Windows version 2405 and later. [CVADHELP-28148] • Citrix Workspace app 2409.10 or higher might terminate unexpectedly after session launch if .NET Desktop Runtime 9.0.5 is installed, leaving only “Open” and “Exit” options in the system tray icon. For more information to resolve the issue, see the knowledge sharing article CTX693370. [RFWIN-38588] • You might experience issues when copying and pasting with Microsoft Office apps (such as Microsoft Excel) in Citrix Workspace app versions 2503–2503.2. [HDX-88750] • You might experience issues when copying and pasting text from Linux Chrome browsers or between VDA sessions in Citrix Workspace app versions 2503–2503.2. [HDX-88060] • If the Desktop Viewer toolbar is selected or focused and you press Alt+F4 (the default Windows shortcut to close an application), the toolbar might close. While this action does not impact your session, the Desktop Viewer toolbar might be no longer visible. [HDX-88180] • Copying files directly from an open VDA session running on version 1912 to another VDA session running on any version using the clipboard might fail. However, copying files from newer VDA versions to older versions (such as 1912) is supported. [HDX-88057] • When using Citrix Workspace app 2503, copying or pasting files might fail on VDA version 1912 LTSR. [HDX-87963] • When using switch desktop to bring a windowed mode ICA session (desktop or application), the session window might remain in a “top-most” state. This keeps the session window above all other windows, making it difficult for users to interact with other applications or desktop elements behind it. [HDX-87102] • The Desktop Viewer toolbar might cause the session to lose focus and remain behind other application windows. As a workaround, click the session window to bring it to the foreground. [HDX-85277] • The devices list in the Desktop Viewer toolbar or the Devices tab in the Connection Center might take a few seconds to enumerate. [HDX-85988] • The deviceTRUST 23.1 Client Extension might load incorrectly when installed alongside Citrix Workspace app 2503. [DEVTRUST-42], [DEVTRUST-69] • The display monitor’s vendor, product, and serial numbers might be missing when using deviceTRUST. [DEVTRUST-53] • You might not be able to identify Intune MDM properties for some devices when using deviceTRUST. [DEVTRUST-54] • You might notice that the location’s country is unavailable if you do not use a geocoding provider in deviceTRUST. [DEVTRUST-97] • The deviceTRUST client extension might display an active setup pop-up when a user logs in for the first time within a virtual session.
