Registry entry not removed McAfee

I recently uninstalled and reinstalled McAfee Live Safe. I used the McAfee removal tool before reinstalling. When I run CCleaner it continually finds the following registry key:

McAfee Installer HKLM\Softwarre\Installer.

CCleaner removes it, but, it just pops up again. When I run System Mechanic it doesn't find it. Anyway, is there a way to remove this entry short of editing the registry something I don't want to do? For the time being I added this registry key to my exclude list? Thanks
