Need Help Reclaiming License After Windows Crash

My Windows system crashed, and I had to do a clean install. After reinstalling CCleaner, it’s asking for my activation key again, which means it’s not recognizing the previous activation and is using up another slot.

The app no longer offers the option to manage my license. Can you please tell me how to deactivate or remove the license tied to my old Windows system so I don’t lose one of my activations?

Thank you.

It is normal following a full uninstall/reinstall of CCleaner to have to enter your Licence key again.
The same key that you already have will still be valid and work with the new install.

If you have not made a note of your key then it will be on your original purchase email, or you can look it up here:
