“My CleanMyMac 3 activation number doesn't work. What's wrong?”

First, make sure that you received your activation number via an email from the MacPaw domain. If it was not from MacPaw, then, most likely, this CleanMyMac 3 serial number is not valid. If it is from MacPaw, copy and paste your CleanMyMac 3 activation code into the corresponding activation window of CleanMyMac 3. 

Then, double-check the activation code in the activation window to make sure it doesn't include any additional symbols before or after the code. If this doesn't help, please contact our support engineers.
