I may have a similar problem. I have High Sierra 10.13.6 on my Mac. Had CCleaner free for Mac installed. Purchased CCleaner Pro and received download link. When I try to install pro version, nothing happens. I have uninstalled all versions and tried reinstalling Pro version. Still no luck. Get following error message when I try to upgrade to Pro: “The registration process failed to save the key file.” Perhaps I am doing something wrong?? Please advise how I can get Pro version up & running. Thank you.
