I have CC Cleaner Pro and in the process of buying another computer. I do I re-install the Pro version on my new computer? I realize I will have to uninstall the program on the old computer.
Make sure you have a note of your registeted name and licence key and then just uninstall from the old one and install the Free CCleaner version on the new one.
Then go to Options>About and click on 'Upgrade to Pro', enter your name and licence key as asked and click 'Register'.
Job done, if you have any problems post back.
