Uninstall registry lockup.

After uninstalling CIS8 and running the Geekbudy cleaner and ccleaner . I still have problems to install any version of CIS . the registry key “HKEY_LOCAL_MACHINE\SOFTWARE\COMODO\CIS\Installer” is not accesable and is stopping installation. Can not delete or edit the key. The Geekbudy cleaner reports as locked and can not delte it.

Please help.

Have you tried using God registry, please note this can easily remove anything after changing permissions of keys so please be careful.

Dennis.

Edit You can also use a command prompt running in admin mode instead of using a batch file.
