Thanks for the reply - you are correct - I found additional registry entries at HKCU\Software|Adobe\Acrobat Reader 8.0. I deleted that, but it doesn't solve the CCleaner problem. I had not only used the Adobe Uninstaller, but manually cleaned files using Windows Search, cleaned with CCleaner, EasyCleaner, and RegSeeker, deleting anything that had Adobe Reader 8.0. As you stated, obviously there are additional files which are still on the disk. I appreciate your response.
