Cleaner keeps closing

Three times, I attempted to FIX several issues and CC Cleaner gets to around 37% and then I get a message that the program has stopped working.

This is the first time in many years this has occurred.

Any idea as to what's going on?

What operating system are you running ?

Which build of CCleaner?

Are you doing a registry clean when this happens?

What anti-virus do you use?

What operating system are you running ? Windows 7 Professional

Which build of CCleaner? 5.20.5668

Are you doing a registry clean when this happens? No, just running Cleaner

What anti-virus do you use? Avast

Please run ccleaner in debug mode

And provide this thread with the resulting log after recreating the crash.
