[hangs at IE history]

My solution (above) did not last long !!  2 days later and it started 'locking up' at IE history/cookies/temp files again.

What I have found is that if you deselect history and temp internet files (first 2 under IE) then CCleaner runs fine.  After it has run once then select those 2 again and run, and it goes fine again.  But deselect before exit, as it will lock up again next time.  First run seems to be the problem.

No idea what/why/how - but that has worked for a few days for me.

[hangs at IE history]

Had same problem for many months - tried many things, including taking ownership of the IE folders.

I dont use IE - only use Chrome. Win 7.

But - found something and tried it - and it worked.

Open MSE (and/or whatever antivirus antimalware) - exclude the CCleaner folder, and exclude the CCleaner processes (.exe).

Worked for me.
