I have new version, and when I start cleaner, it shows Internet Explorer, Temporary Internet Files, and timer spins, but doesn't proceed any further,,, It worked before, but now I don't know, I've waited 5, 10 and now 15 min before cancelling
"New version" doesn't help, please provide a version number as well as windows version.
Try deleting internet explorer's junk from within ie then run ccleaner again (could be that ie has a corrupted dat).
If this doesn't work, please run ccleaner in debug mode and post the resulting log to this thread.
