After instelling PSE450W2K3R06 on a XenApp Server 5 an application is crashing.
The application no longer works in the desktop and even as a published application.
The application does not give an error. Nothing to find in the eventviewer.
If the application is started you can see in Task Manager that the executable is open, but after a few seconds it's closed.
Several things have changed, but unfortunately no success.
1. Speed Screen off.
2. HKEY_LOCAL_MACHINE \ SOFTWARE \ Citrix \ CtxHook \ AppInit_DLLs \ Multiple Monitor Hook adjusted.
The application starts with a Splash Screen. I suspect therefore that Citrix uses a technique that is keeping the application to start.
The application works fine in RDP
If the hotfix is removed the application works fine in ICA and RDP.
Anyone have any ideas?
