That's it, I'm trying to remove the software remotely, it works fine on test machines, but I have problems with production servers. test machines I used windows xp, windows 2003 server,
production machine: Windows Server 2003.
what could be causing this error, any help would be much appreciated. If you have another way to unistall the software on a remote PC, share it.
