Purchased MakeMKV Question

[XrayDoc88]

I'm a long time user of "Beta" MakeMKV. I've decided it's time for me to share some love with the developer. I currently have MakeMKV installed on three different computers in two separate homes. I only rip a movie on one computer at a time, depending on my location. Will the purchased key activate all three personal installations? Or will I have to deactivate/uninstall a previous installation to use it on a different computer? Or to avoid that, do I have to purchase 3 separate keys? That would be a little expensive.

Thanks!

One key for all 3 is fine it licensed per user not per PC
