I have received several messages telling me that I have to register my account for CCleaner professional. I have the key but I have not seen a place for registration after following the direction I have received. What do I do?
Open CCleaner.
Click on Options left hand side.
Click Upgrade to Pro at the top.
Enter your key making sure to do it correctly (copy and paste is usually a good idea)
