Hi all, I have (had) a lot of problems uninstalling drivers when i want to try out new sets (and switching back if they didn't answer to me). The major issues i had was when i rebooted after uninstalling the drivers, windows just reinstalled them without asking or initialising the "found new hardware"wizard and i had to delete some "oem.xxx" files from the sysfolder, editing the registry (even regcleaner didn't remove all keys) and so on just to be able to get a clean driver install. Following the uninstall guide, i only managed it once (after trying for about ten times) to force winxp to (virtually) remove the hardware and to be able to do a clean driver install. I'm still using the catalist 02.2 (6159) set because i can't remember how i've managed to get a clean install (lucky shot.. hehe) If ATI is able to make such great "install" software i'm sure they are able to make great "uninstall" tools which are included with new (catalist) driverpacks. I'know Omega is.. just a suggestion. Cheers, T.
