Hello, I purchased the ccleaner pro 3 days ago, but now i get a message "Fake Serial Number". Kindly help me in this regard, because I paid for the Pro version and now it shows like I'm using cracked version....
Are you referring to this "your licence key is invalid" message?
This can happen if:
- Your licence key is cancelled after you request a refund
- You have an old expired licence that has been replaced with a new licence
- Your licence was cancelled for abuse - if you buy a 3 PC licence and use it on a dozen machines, for example.
Assuming that you haven't requested a refund (Scenario 1); and you haven't purchased your CCleaner licence from some shady third party key warehouse (the most common source of Scenario 3), I am assuming that you previously had an old CCleaner licence key in there and bought a new one (Scenario 2)? Go to Options > About > License Information in CCleaner and check to see if it is an old licence key that is still in there that needs to be updated (check the key itself, not the date, since cancelled keys have their expiry date reset to NULL, which renders as 1 Jan 2000). If you can't remember which licence key is which, you can get a list of all of the licences in your name here: CCleaner.com - License Lookup
And if all else fails you can contact customer support at support@ccleaner.com - ideally using the email address that you used to order from us and/or providing your Cleverbridge order number and/or the licence key in question - and they can assist you further.
