Changing from windows to os

Hi, I ve changed my computer from pc to iMac and I have a ccleaner key for windows. I asked and received my product key for email but when I install the ccleaner for mac I didn't find where to put it and use the full product.

I hope I can use the product even changing platform.

Thanks

I'm not sure if you are saying that you now obtained a key for CCleaner Mac?

If you do then AFAIK you enter it in the same place as with the Windows version.

Options>About>Upgrade to Pro, enter your registered name and key and click the Register button.

To avoid typing mistake copy/paste from key from the email.

On note: I don't think windows keys are going to work on Mac

The single computer CCleaner Professional licence keys (which start with the letter "C") are each for for Mac or PC - but not both. CCleaner Professional Plus licence keys (starting with the letter "P") work on both Mac and PC - https://support.piriform.com/hc/en-us/articles/360028350711-How-many-computers-can-I-install-CCleaner-Professional-Plus-on-
