Hi. Been using CCleaner for many years without any problem until 3-4 days ago. If I run the cleaning scan, at about mid 95-96% progress, it stops working. A pop up window that reads "CCleaner has stopped working. A problem caused the program to stop working blah blah blah..." appears with a "Close Program" button. I believe this problem started happening after a windows update around that time. I uninstalled Ccleaner, rebooted laptop, and installed a new copy . Problem still remains. I'm using Windows 8.1 64-bit. Thanks for any help in advance.
