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
If you're using any add-ons such as winapp2.ini or some "enhancer" try removing them to see if that helps. If you don't using of those uninstall CCleaner, reboot, and then reinstall CCleaner by downloading it from Piriform at: http://www.piriform.com/ccleaner
Yea, I've done a clean vanilla install. It can now start Analyzing, but it has been scanning only a handful of files per minute. Been at 0% for 10 minutes now.
Can you run ccleaner in debug mode and provide the log it creates, maybe that'll help. (I've got nothing to go on here yet, I'm definitely not experiencing this on my win 8.1 box)
