Windows and Mac dual use?

[MarcoR50]

I just bought ArtRage Vitae from the Microsoft Store. Do I need to buy it again on the Mac Store if I want to use it on my MacBook Pro?

With ArtRage 6 it was possible to use the same license on booth systems!

We're not able to do cross-licensing between the Windows Store and the Apple App store.
That does mean you will need a second license to use ArtRage Vitae on both platforms.
