Registry items deletion failure

[eraserhead]

Did not find references to dial-a-fix permission tool on first search.

Please disregard post.

Perhaps my issue is that I am running Windows 2K. CCleaner finds 110 registry entries with issues. When I try to fix the selected entries, they appear to get deleted, but if I run the utility again, they are still there.

 

I am running Zone Alarm FW, AVG antivirus, and cannot figure this one out. I suspect this may be due to some other program, but any help I can get would be appreciated.

 

Thanks.

More info: I have admin rights and I did check permissions. I checked and cannot delete keys in regedit or regedt32, so the problem is not CCleaner. Is anyone aware of other ways registry access/editing is denied?
