dude, understand before saying they're wrong. "\%systemdrive%" indeed does NOT work, HOWEVER he has "\"%systemdrive the \" escapes the quote so that it is imported into the registry properly, because ""%systemdrive%\Program Files\setup" /qb" does NOT work. if SmokingGun's thing doesn't work, remove the cmdow @ /hid at teh beginning and retest. You probally have a prompt somewhere waiting for a response (missing /f perhaps_)
