Catalyst Control Center keeps reverting back to older version?

I bought a pre-built desktop a little over a year ago. It cam with integrated graphics, an ATI Radeon 3000. I installed an HD 6670 shortly after. I now have a two monitor setup. I have my primary monitor hooked up to the 6670 and the secondary to the 3000. After updating CCC to 12.6 from 12.4 the second monitor isn't detected.

I've been going to device manager and uninstalling the 3000 drivers, then restarting, and my secondary monitor is detected, drivers auto install, and both work. Unfortunately when I check CCC it's back to 12.4.

Thanks in advance!

You need to get rid of the old ccc registry values, driversweeper does a good job, I use that with ccleaner and it usually fixes those type of issues

I'll give it a shot, thanks.
