Catalyst Control Center problem

I just tried installing Catalyst 7.12 without uninstalling 7.10 as I thought that it would work. 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 Flight Simulator 9 has no AA and AF at all without CCC open.

Hi, that is what I did. Even 8.1 won't fix it.

Well you are using the second worst software on the planet, second only to nTune.

hi guy. hey, i bombed hard for days w/ ccc, even 8.1 bombed 4 me. finally, i hassled techies enuf 2 get instructions. basically, u gotta go into the registry, and find anything that refers 2 ati, and delete it, so ati is not known in your registry (usu u find stuff from prev installs.) then, u gotta go and lookup .inf files, they would be ones w/ a second part 2 match the .inf itself, and delete any of them that refer 2 ati. 4 me, there were about 20 .inf files 2 consider, i only nuked 3. sorry, but if this doesn't work, run this by ati support, and they'll tell u about the same thing, but super direct/accurate(er) than me. ps/ i am gonna bomb & drop ati, like a hot potatoe, as soon as displayport comes around. now i've oc'd my rig, and ccc loses altogether its host processor, so i can even look at my gpu temp (that's all i use ccc 4 anyway. adios, cooky.
