ATI Catalyst Control Center Woes

On more than one occasion, we’ve seen ATI’s Catalyst Control Center (CCC) crash on startup and a uninstall/reinstall does not correct the problem.

After numerous searches, we came across the following steps that worked for us. Since this involves modifying the registry and other configuration information, proceed with caution as it may not work for you. In other words, make a backup or set a restore point at the very least:

  • Uninstall CCC via the control panel.
  • Ensure the following registry keys are blank:
    • HKCU/Software/ATI/ACE
    • HKLM/Software/ATI/ACE
  • Confirm c:\Program Files\ATI Technologies\ATI.ACE is empty
  • Review the c:\Windows\Assembly folder to see if any files with a public key token of "90ba9c70f846762e" exist. If so, remove by by right clicking and selecting Uninstall.
  • Confirm the appropriate (User)\AppData\Local\ATI\ACE folder is empty (folder location may vary depending on OS version.
  • Reboot and reinstall CCC.
