CCleaner has stopped loading

My CCleaner has stopped loading and working.

What should I do.

@MDK1 We'll need a little bit more information in order to assist you:

  • Which version of Windows are you running? If Windows 10, do you know the Windows 10 version number?
  • What is your present CCleaner version number? Is it a free, paid or trial copy?
  • When did it stop working for you? Was there anything that you installed or changed on your system prior to CCleaner stopping working?
  • Will your existing installation of CCleaner run if you go to C:\Program Files\CCleaner, right-click on CCleaner64.exe and select "Run as Administrator"?
  • What happens when it stops working? Does it appear and disappear after you run it or does it fail to load entirely? Are any error messages displayed?
  • Which AV are you using, and when did you last update it?
  • Are you using a firewall or a custom etc/hosts file and, if so, have you added any rules to block CCleaner?
  • Have you tried installing a fresh copy from https://www.ccleaner.com ?
