Just upgraded CCC from the box version that came with my 6850. The new CCC version is not detecting my 2nd graphics card, a 4650. Doesn't show up under CCC information\Hardware.
Radeon HD 6850 PCIe x8
Radeon HD 4650 PCIe x8
The card does appear in windows Device manager under "Display Adapter" as "ATI Radeon HD 4600 Series" , but properties window says "Windows has stopped this device because it has reported problems. (Code 43)".
I'm hoping that there's a good solution, other than revert back to old software.
Edit: downloaded from 11.8 page, appears I installed 12.10.
