I've upgraded CCleaner for Windows, but i have to enter the license key every time the computer restarts. I've done the "run as administrator" thing, but that doesn't fix the problem. Any ideas?
We've seen it before a couple of times.
If you contact support by email and explain the problem they should be able to either sort it out or issue you with a new license.
Email them at:
@Eric S: and when you do, please confirm with them what version number you are using (top left hand corner of your CCleaner console, should be CCleaner 5.75.8238 if you are on the latest version)
