When I first posted here, I was having a problem with CCleaner taking forever to load and run. After trying uninstalling and downloading again and still having the same problems, I finally found that if I didn't use the desktop or taskbar shortcuts and ran it directly from c:\Program Files\CCleaner\CCleaner64 the program runs fine. So I'm assuming the short cut options (add shortcut to...etc) when downloading is the problem.
I've been having the same problem. I tried uninstalling CCleaner and downloading again and reinstalling but that doesn't solve the problem. Hopefully someone out there knows what's going on?
