What needs to be done?
People do get new machines, so transferring the CCleaner subscription is simple to do.
Just install CCleaner Free on the new machine, go to settings > My Subscription, and enter your licence key to activate it as CCleaner Professional.
You can download an installer for the latest version from here:
Once it has been activated with your key on the new machine then, unless you have a multi-device subscription, (Pro Plus, or Premium), you should uninstall CCleaner from the old machine
You can of course put CCleaner Free on the old machine.
Thank you so much - it worked
