Upgrade to Professional is not working

Recommended Posts

Hi - I have just paid for the upgrade to Pro and it has not gone well !!   I get the message as in the attached screenshot.  Nothing happens if I retry and if I ignore then its carries on and appears OK.  It appears to work but it is in FREE mode only.

Any suggestions would be helpful please.

It's a common issue and is caused by CCleaner still running in the background, as CCleaner64.exe is still running the upgrade can't replace it.
