I purchased the professional bundle and it downloaded and installed fine. How do I add cleaner to a second computer?
Download the installer for CCleaner Free: https://www.ccleaner.com/ccleaner/builds
Install CCleaner Free on the second computer.
Go to Options>About>Upgrade to Pro.
Enter the name/key as asked and click on 'Register'.
Thank you Nukecad, I will give it go.
