how are you dealing this? I'm having always trouble with Citrix Receiver when I need to update existing versions. It looks like receiver setup does restart WMI, I see ccmexec is restarting and returns: "The program was able to be executed but the system was restarted unexpectedly before the program could be completed or before status could be recorded" although installation was successful. because of this "error", neither SCCM Client does restart the PC nor receiver setup does (suppressed if using /silent switch)
thanks Reto
