My old computer died, and I am trying to enter the CCleaner Pro licence into a new computer. It seems to accept, but as soon as I restart the computer or open CCleaner again, it has reverted to the unlicensed free version. Can anyone help?
@Mark1960: Best to check licence-specific issues with support@ccleaner.com. But this sounds like an issue that was specific to new format CCleaner licence keys (the ones that don't start with a "C" or a "P") on versions of CCleaner 5.74 and below. Check your CCleaner version number (top left hand corner of the CCleaner console) and if it is 5.74 or lower you can grab the latest CCleaner Professional (5.76 at the time of writing) from https://www.ccleaner.com/go/get_ccpro
