Report Wise Registry Cleaner Freezes in Wise Registry Cleaner Posted July 5, 2013 Hi there, I've been using Wise Registry Cleaner for a while now but recently I formatted my PC and now I can't seem to use it anymore. Every time I try to do a scan, it freezes in the HKEY_CLASSES_ROOT\ActivatableClasses entry. It just sits on that entry without any progresses. Any ideas? I'm on Windows 8 x64. Thank you.
