Common Errors on the Microsoft Application Virtualization Client

The following sections list the most common errors encountered with Microsoft Application Virtualization

Desktop Client and the most common solutions to those errors.

1.When you attempt to refresh the server you get an error that says, "The client failed to download..." and "The server could not authorize you to access the requested data..."

2.The application shortcut is not on the Microsoft Application Virtualization Client desktop.

3.The application did not stream to the Microsoft Application Virtualization Client. If the application fails to stream you see the "Launch Failed" error message above the notification area.

Possible Causes

1. The user account used to log on to the Microsoft Application Virtualization Client is not a member of the Microsoft Application Virtualization Users group or is not a domain user account.

2. The .sft, .ico, and/or .osd files are not in the Microsoft Application Virtualization Management Server “content” folder. Copy these file to C:\Program Files\Microsoft Application Virtualization\Microsoft Application Virtualization Server\Application Virtualization Server\content.

3.There are typing errors in the .osd and .ico paths in the application record in Microsoft Application Virtualization Management Console.

4. The Microsoft Application Virtualization Client cannot access the “content” directory on the Microsoft Application Virtualization server. Check the permissions settings on the content share.

5. The Microsoft Application Virtualization Client cannot access the Microsoft Application Virtualization Management Server. Check network settings, cabling and firewall exceptions for the server services.

6. The “content” folder on the Microsoft Application Virtualization Management Server is not set to share or to be shared with everyone who has read access.

7.The Microsoft Application Virtualization Client is not a member of the domain.

8.The user lacks necessary permissions to access the application. Reread and follow the procedure regarding importing .osd files, paying close attention to setting the access group.

9.The operating system of the Microsoft Application Virtualization Client computer is not listed in the .osd file of the application.

If none of the above appears to be the cause of the problem, check the Microsoft Application Virtualization Client log (Sftlog.txt) in Desktop Client for errors. The file can be found here:

-->C:\Documents and Settings\All Users\Application Data\Microsoft\Application Virtualization Client: Windows XP, Windows Server 2003

-->C:\ProgramData\Microsoft\Application Virtualization Client: Windows 7, Windows Server 2008

  1. Great documentation.

    May I suggest that you add the firewall ports that need to be opened for the client to communicate with the server? Windows 2008 R2 brings the firewall turned on by default, so if someone follows your documentation, they'll soon find out that clients do not 'talk' to the server due to the firewall on the server.

    1. Hi Edward,
      If it is Windows Firewall,you can either Disable it Via Group policies to disable the firewall.
      If there is something issue with client to communicate with management server over ports like HTTP,RTSP,RTSPS or HTTPS,you should really look at them if they are opened or not or contact network administrator.

      Default ports for each protocol type:

      RTSP= 554

      Please read for more information on How to troubleshoot applications failing to stream from an App-V management server
      and Troubleshooting Common RTSPS Issues with App-V
