The generic usual suspects for a problem like this would be:

  • Did you buy CCleaner Professional for the PC and tried to enter the serial onto a Mac?
  • Did you copy-paste your serial number from the email instead of typing it in - those capital letter "i"s can look a lot like "1"s on most screen fonts, so it is easy to make a mistake when typing it in by hand.
  • ... and, as happens now and then ... did you buy from Piriform/CCleaner/Cleverbridge or from some shady fellow on eBay offering a too-good-to-be-true cheap price?
