Enter the licence number in CCleaner itself not on the forum
Licence key can be found in your confirmation email after purchasing. If you have lost your confirmation you can recover your key from https://www.ccleaner.com/support/license-lookup.
For CCleaner for PC you can enter the key under Options > About > License Information. Be sure to copy and past your email and key from your email, as transcription errors (mixing "Z" and "2", etc) are a common problem.
