  1. Actually, here is a more direct link to the page needed. Using your email address, Piriform will email you the registration key and download link to reinstall. Proceeding through the various FAQ pages will ultimately bring you to this page (using "I've lost my product license key"): http://www.piriform.com/support/ccleaner#204044264
  2. Note - Since I was already a Pro subscriber, I was hesitant to just Download Pro for the reinstall, fearing that I would have to repurchase and start over. This link uses your email address on file to email you your current registration key, with a download link. ("I've lost my product license key"). I suggest this route could be the easiest fix. http://www.piriform.com/support/ccleaner#204044264
  3. The uninstall/reinstall fixed the Windows 10 problem for me. I used the link above to get the registration key from Piriform. CCleaner is now functioning again. The fix was quick and simple. Thanks to all for your very helpful advice.
  4. Thank you! I suspected that might fix the problem, but thought it prudent to ask first. The uninstall was fast (via Windows Settings menu). With the link below, Piriform emailed me the registration key for my Pro version. I downloaded the new software and installed it, all in a few minutes - the latest version 5.25.5902. CCleaner now runs perfectly for me. If only all of life's problems could be solved this easily. Thanks again for your help, and thanks to Piriform for making the process simple and effective. http://www.piriform.com/docs
  5. Windows 10, 64 bit version, updated automatically this morning. Now when I try to load CCleaner, I get message that "CCleaner doesn't work on this version of Windows." First time for this message. How do I resolve this for CCleaner to run?
