Citrix XenApp

Microsoft Windows 7 and Citrix Receiver not launching certain apps from Web Interface


Windows 7, Citrix Receiver 3.0, 3.1, 3.2 etc., and Web Interface 5.4 all work hand in hand with newer XenApp farms. But you might notice if you have older farms in your Web Interface, apps from those farms will not launch when using Windows 7 and Citrix Receiver. You’ll get a message like this when you click on an app icon:

The network connection to your application was interrupted. Try to access your application later, or contact your help desk.

Really helpful right? Well if you look at your event log on your Windows 7 box, you get something even more cryptic:

The description for Event ID 1 from source ICA Client (Vanadium)
cannot be found. Either the component that raises this event is not
installed on your local computer or the installation is corrupted.
You can install or repair the component on the local computer.

If the event originated on another computer, the display
information had to be saved with the event.

The following information was included with the event:

Vanadium: TW Protocol error: Data rejected
The data containing the error is below (1953 bytes)

I get this error with apps hosted on legacy MetaFrame XP and Presentation Server 4.0 farms. The work around is to go to your farm’s console, right click on your farm name, Properties > ICA Settings and uncheck the “Discard redundant graphics operations” setting.

After making this change, the apps will launch just fine. Additionally on some MetaFrame XP apps, I’ve had to go under the actual published application properties and lower the resolution of the app. I doubt Citrix will ever release a fix for this since legacy farms are not supported and reached End of Life years ago. You should get your apps moved over to newer XenApp farms as soon as possible.

    Jason, Great site but have you had success using the 3.2 client with a ps4.0 farm?

    Yes, we have had no issues. But 3.2 had several other issues and I ultimately decided to to roll it out to our users. 3.3 has fixed many of the issues we had and works much better with older farms and so have rolled that out instead. Try 3.3 and let me know if it works better for you.

    Thanks for the update. I’ve tried 3.3 with Legacy PNA and WI 5.4. Get the icons on the desktop but then clicking them gets ‘The remote server failed to execute the application launch request’ Nothign obvious in the event logs.
