So I've run into this problem where I can't run CCleaner's Cleaner (redundant, meh). The other tabs etc work fine, but it just sits on infinite loop loading Windows/Applications... the log doesn't show anything interesting.
It also is doing anything else extremely slowly; I've been running registry cleaner for 5 minutes and it has barely progressed
Sigh, also, the uninstaller is hanging
EDIT: Reinstall got it working, but it is very slow
