I upgraded my current ccleaner MAc version to Plus, to be used on 3 macs. However I have received a link for Windows, not for Mac. So how can I change this?
You will need to contact support and they should change it for you with no fuss.
There is a form you can fill in here: https://support.piriform.com/hc/en-us/requests/new
Alternatively you can email your support question to: support@ccleaner.com
Thanks, will make contact with them
