Can I use Win serial for Mac?

I have registered the pro version of CCleaner on Windows. Now I got an iMac and I'm wondering if I can use my Windows serial to register CCleaner on my Mac, and if so, how?

I don't believe you can, but you might want to directly contact the devs as this is a user forum and the devs rarely poke their head in here

Ill do that. Thanks :)
