Yes i was in safe Mode

Were you in safemode when you tried to remove the driver?

Reload the older Catalyst, then download the free version of Revo Uninstaller   HERE   use that to uninstall the ATI Catalyst program as it will remove left over files and even registry entries.  Restart the PC and then install the new version.  This MAY get it installed.   I used this with one of the "corrupt" versions (I think 10.4) to get rid of it so I could reinstall 10.3.

I'm still on 10.3 as later versions of the drivers cause several older games (and I only have one game and it's affected - Soldier of Fortune) to not work.  Some of the later versions did not install and finally 10.7 installed but it caused the game not to initialize so I'm back to 10.3/drivers.  There are several threads on the Windows 7 forum about the ATI/Radeon drivers and some have even reported dumping ATI and going to Nvidia as all of their drivers work with older games and/or are not buggy.

Well I thought the problem was solved because their wasnt a trace of the driver nor CCC in any files nor the registry so I was confident. However, loade 10.8 drivers again and everything said installed sucessfully. Well CCC still wont open, I honestly think this is a problem with CCC itself rather than the insallation. I would hope ATI in their 10.9 drivers would fix this, because some of us need access to our Graphics Cards Fan controls. And for me Riva Tuner would not work.

SUCESS!!!!!

Everyone the problem has been solved thanks to a person on another blog in hardware heaven. Click this link to get more information http://www.hardwareheaven.com/mobility-radeon-drivers-support/186707-problems-installing-catalyst-control-center.html

Or

Uninstalling CCC, and then:


1. Check that (Program Files folder )/ATI Technologies/ATI.ACE is empty
2. Check (Windows folder)/Assembly folder to see if there's any files with Public Key Token of "90ba9c70f846762e" (Sort by Public key token to get a easier view). All these tokens should be uninstalled by right clicking and uninstalling.
3. Check that (Document and Settings)/(User)/AppData/Local/ATI/ACE is empty
4. Reinstall CCC

Those are the steps that i followed and it worked. Also ATI released their 10.9 drivers today so i used them after these steps and installation was beautiful. But seriously most people would have no clue how to do this. ATI needs to step up in their game especially since they are making a huge comback on Nvidia just look at the stocks of Nvidia they have went down nearly 50%. But there are the instructions to do it. I would do this in Safe Mode also. Then install the 10.9 drivers

I found that directory and those files but when I right click and uninstall they all say access denied and won't let me remove them.  I am logged on as administrator and dont know what to do next?  Thanks

If you read the instructions further on the other website, he concludes that it did not work for him either.  If I could just get into CCC then I could fix the screen flickering problems whenever I try to use any software with a 3D application which is probably 99% now.

Hey, anyone from Dell out there that can solve this issue?  I know the tech support guy I called in India was clueless.

Just spent the afternoon dealing with the CCC not loading after updating my drivers.  Simplified version of what I did...

1.  Uninstalled all the ATI stuff I had tried to install.

2.  Booted into safe mode so I could uninstall all those GAC entries.

3.  Booted again into normal mode and installed the 11.11 drivers.

4.  CCC launches now.

The app has changed quite a bit in its interface.  I noted none of the GAC entries came back so they obviously were not needed.

I'll note that I briefly panicked when trying to install the new drivers while in safe mode.  The ATI installer reported it could not load the driver to detect the hardware - and hung.  I crossed my fingers and rebooted.  On to step 3.  The installer worked normally at this point.

Given al the issues with ATI/AMD (I too cannot get CCC to open to adjust scaling for my Radeon HD5450 to solve an "image doesn't fill screen" issue) I may just dump it all and go with nVidia. If I install a new video card and new drivers will that resolve my issue?
