3 pages and nobody pointed you towards Driver Sweeper!?
ATI graphics drivers are notoriously buggy... they always have been and everyone here knows it. Installing one driver over another is never a good idea with ATI drivers... you're just asking for trouble.
It's a hassle, but if you follow this method you will be a happy camper.
First: download and install Driver Sweeper. Guru3D - Driver Sweeper
Second: Uninstall through Add/Remove, select express uninstall of everything. After the drivers have uninstalled answer yes to uninstalling CCC. Reboot when prompted and tap the F8 key to boot up in Safe Mode.
In safe mode run driver sweeper. Check ATI and let it clean all traces of previous drivers. Reboot when done and install the latest.
Well Driver Sweeper seems to have removed the ATI drivers, but when I try to install 10.11 I still have the problem with Program Compatibility Assistant.
I finally got to 10.11 installed. What I did was I went through Windows' driver update and it installed 10.11.
Thanks for all the help everyone!
You got lucky, really.
Windows update can only give you drivers given to them... it doesn't seek out the latest drivers. Sometimes the drivers they have are dated, which is why it's always recommended to seek out the drivers on your own.
I'm curious about the Program Comparability Assistant though... it's for older programs, so it should not have popped up installing drivers that came out a few days ago.
Yes I'm curious as well.
As for the Windows update, can't you simply download the latest and point Windows update to it as opposed to it going online looking for the latest drivers? I tried doing that but in this case the one online was the same as the one I pointed it to.
