Adding Ccleaner to second computer

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'.
