Since the new version was installed, I am also having trouble. CCeaner is installing completely, but crashes when it is running the Clean. I've read thru the posts here and have tried everything except doing a Window 10 recovery to an earlier date.
UPDATE: I don't use Google Chrome, but I have it installed. When I turned off the Chrome CCclean, no changes... the program still crashed. Then, with Chrome off, I turned off Firefox. CClean finished the scan... ok.... then I started with Firefox and started rechecking ONE box ant a time instead of all under the Firefox tab.... CClean continued to run perfectly until I checked and ran with "Internet History" or with "Internet Cache" checked. Then CClean failed until I turned off the "Internet History" or the "Internet Cache" checkbox(s)... hope that helps you guys.
