When trying to launch a published application in XenApp 6.x, the following screen appears for a minute, then disappears without launching the application.
This is because the default XenApp 6.x application launch timeout is set to 60 seconds. The resolution is to set the timeout to a greater value using the following registry key:
Key: HKLM\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI Type: REG_DWORD Value Name: LogoffCheckerStartupDelayInSeconds Value Data: 600
The example above sets the application timeout to 10 minutes. (the value data is in seconds)
