Run Time Error "6" Overflow in CCleaner Bug Reporting Posted December 14, 2006 Now that I've looked, a few others are having problems also. The last thing I can suggest is reboot after you install the update. If that doesn't work, you can try going into Safe Mode. Still no joy...started in Safe Mode after installing the recommended Microsoft update. CCleaner starts the Analyze process, then freezes with the Run Time Error. Any other suggestions from anyone? I'd sure like to run this software.
