One thought is that the auto-workstation install is attempting to start (due to something that changed and made the installed files out of synch) but is unable to. Try running the workstation setup in \softrak\apwin\wksetup\wksetup.exe and see if that helps.

I suppose one problem is that the Crystal Reports install changed something in the \qrasp directory, though I would have expected different behaviour than what you are experiencing.
