Registry Cleaner

I have two computers running Win XP Home SP2. I recently uninstalled Winzip. I have run CCleaner registry clean up numerous times on each computer. Everytime it finds the same issues with Winzip. I remove the registry entries. But th enext time I run CCleaner they are there again - on both computers. What can I do to permanently delete these registry entries.

Thanks

I fixed the problem. I used the registry cleaner in Clarity Utilities to permanently remove these registry entries. For some reason CCleaner is incapable of doing this.
