Hi, I just tried installing Catalyst 7.12 without uninstalling 7.10. After that, CCC will not open at all. I tried uninstalling every trace of ATI and even did a system restore but after the system restore, every time i open CCC it gives me the "has encountered a problem and needs to close" error. Please I need some help as FS9 has no AA and AF at all without CCC open.

Hello SQ,When uninstalling the Cats, did you also use driver-cleaner to really get rid of all traces usually left behind after just a normal uninstall, before re-installing?Regards,
