Known issues 编辑

The Citrix Virtual Apps and Desktops 7 2106 release contains the following issues. Components and features that are documented separately have their own known issues articles.

This warning applies to any workaround that suggests changing a registry entry:

Warning:

Editing the registry incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.

Install and upgrade

• When upgrading a deployment to this version, the compatibility check incorrectly reports “Required Customer Success Services Date: 2021-08-15”.

  If you see this message, and your Customer Success Services date is at least May 15, 2021 (2021-05-15):

  • Proceed with the upgrade if you’re using the installer’s graphical interface.
  • If you were using the command-line interface, start the installer again, using the graphical interface.

• In a command line VDA installation that includes the WEM Agent and specifies WEM Cloud Connectors (/includeadditional "Citrix WEM Agent" /wem_cloud_connectors "name1, name2"), the WEM agent is installed, but the WEM Cloud Connectors configuration is not processed.

  As a workaround, after the VDA installation, run the WEM configuration utility (AgentConfigurationUtility setup --cloud --connectors "name1, name2").

  This issue does not occur when using the VDA installer’s graphical interface or when you have an on-premises WEM deployment.

General

• When you disconnect a user session from the first endpoint and then reconnect to the same session from the second endpoint (thin client), the client side audio devices might be listed in an incorrect order within the VDA.

  To enable the fix, set the following registry key:

  HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Audio

  Name: CleanMappingWhenDisconnect

  Type: DWORD

  Value: 1

• If you install Citrix Workspace app on the VDA and upgrade the VDA, the client webcam may not properly redirect 32-bit applications running in the virtual session. To work around this issue, see CTX291350. [CVADHELP-16854]

• After you run the Modeling wizard to produce a report of the modeling results, Citrix Studio stops working. To use Citrix Studio, you must restart Studio after you run the modeling report. [GP-753]

• If you launch the app bar and then open the Connection Center menu in Citrix Workspace app for Windows, the app bar doesn’t appear under the server that hosts it. [HDX-27504]

• If you use Citrix Workspace app for Windows and launch the app bar in a vertical position, the bar covers the Start menu or the system clock tray. [HDX-27505]

• If you try to add a protected app to your Favorites, this message might appear, “Your apps are not available at this time…” When you then click OK, this message appears, “Cannot add app.” After you switch to the Favorites screen, the protected app is listed there, but you can’t remove it from Favorites. [WSP-5497]

• In the Chrome browser with browser content redirection in effect, when you click a link that opens a new tab, the tab might not open. As a workaround, select Always allow pop-ups and redirects in the Pop-ups blocked message. [HDX-23950]

• After installing the Skype for Business Web App Plug-in, webcams might not be enumerated and meeting pages on Firefox might not refresh automatically. [HDX-13288]

• When you start an application from StoreFront, the application might not start in the foreground, or the application is in the foreground but might not have focus. As a workaround, click the icon in the task bar to bring the application to the front or in the application screen to bring it to focus. [HDX-10126]

• When you connect to a new session, disconnect, and then reconnect to the same session, your desktop icons might flicker. As a workaround, reset the user profile, log off from the session, and log on again. [HDX-15926, UPM-1362]

• When using Windows 10 1809 LTSC, VCLibs dependencies fail to install. [HDX-16754]

• The combo box might not display properly when a user selects a combo box that is already in focus on the host. As a workaround, select another UI element and then select the combo box. [HDX-21671]

• You have enabled Local App Access. If you start a Windows 2012 R2 VDA session, disconnect and reconnect the session, and then start a local application and maximize it, the VDA taskbar might truncate the application. [HDX-21913]

• When you modify a VDA installation using the full product installer, you can add MCSIO storage optimization to the installation by selecting the option Enable MCSIO write cache for storage optimization. The installation proceeds without installing the MCSIO driver. [HDX-21754]

• When you use generic USB redirection to redirect a composite USB device that contains a mouse as a subdevice into an RDS session, that device might not be available. The most common such device is a Wacom drawing tablet (not Wacom signature pad). As a workaround, manually start icak2meng.exe in the session after logging on. We suggest creating a group policy for Windows Multi-session OS 2016 or 2019 (not needed for Windows 10) that automatically starts C:\Program Files\Citrix\HDX\bin\icak2meng.exe. Create the policy to start the program in each user’s session as they log on. Only one instance running in each user’s session. The workaround is not need [HDX-25085]

• When your network has IPv4 and IPv6 addressing configured, a delivery group’s resources might not be accessible when the group uses a broker access policy rule that allows only IPv4 address filtering. To ensure all resource filtering behaves as expected, configure the broker access policy rule to include both client IPv4 and IPv6 addresses. [WADA-7776]

  For example, to set rules allowing IPv4 and IPv6 addresses via ‘direct to StoreFront’ and ‘Citrix Gateway’ access, use PowerShell such as:

   Set-BrokerAccessPolicyRule -Name "Apps_Direct" -IncludedClientIPFilterEnabled $True -IncludedClientIPs @("10.0.0.1","2001::3")
   Set-BrokerAccessPolicyRule -Name "Apps_AG" -IncludedClientIPFilterEnabled $True -IncludedClientIPs @("10.0.0.1","2001::3")
