how do i fix windows 7 Catalyst control center host application has stopped working

ALL THIS IS SWELL BUT FOR SOME1 LIKE ME i DONT KNOW WHAT IT ALL MEANS.

i AM NO COMPUTER LITERATE.

I just got an answer from AMD for a known problem with Catalyst Control Center and Windows 7.  Here you go.  It worked for me the first time after a lot of troubleshooting.

 

How to resolve CCC not loading/opening when initializing it.

 

Scenario: The user attempts to open/load the CCC through various methods, but it fails to load. The issue may happen with no changes to the system or a Catalyst driver update or reinstall. This is issue mainly affects Windows 7 machines.

 

Cause: Possible corruption of the Windows Global Assembly Cache (GAC). This usually requires the user to format and reinstall Windows.

 

Resolution: This solution has been tested - reproduced and resolved.

 

Remove all ATI through programs and features in the Control Panel using the Catalyst Install Manager (CIM). Reboot the system in safemode and do the following:

 

-          Delete all ATI folders in C:\programs files and C:\programs files (x86)

-          Go to C:\Windows\assembly and sort by "Public Key Token". Locate the following Public Key Token "90ba9c70f846762e" that is

-          associated with ATI. Usually only 2 entries. Delete the 2 entries. Note: the entries should be deleted (right click and choose uninstall) in safemode since regular

-          mode may result in a permissions error. The 2 entries only show up in systems affected by this issue. This means that searching for the 2 entries on systems where CCC loads, the entries are not there.

-      Shut down and re-start normally.

-          Reinstall the ATI Catalyst package.

 

Hopefully this will get you back in working order!

I have followed the instruction from this blog and able to fix the issue :-

I have this exact issue, tried to follow the steps provided except I did not have the listed public key tokens. after uninstalling and deleting everything ATI as the rest of the guide suggests and reinstalling my problem still persists.

Uninstall the drivers in programs and features, then download the drivers from the ATI site.

Dont get the drivers from windowsupdate, if theyre there. Get them from whoever made the videocard
