I bought the Artrage Vitae from the Microsoft store, But, How do I register?

This isn't quite correct. If you purchase ArtRage Vitae through the Windows or Apple Stores you dont need to do anything with serial numbers or registration keys. As soon as you complete the purchase of ArtRage Vitae the Windows Store and Apple Store will automatically download and install ArtRage. On Windows you will have a new ArtRage Vitae icon in your Windows Start Menu. On MacOS you will have a new ArtRage Vitae icon in your LaunchPad (you may need to scroll a couple of pages if you have lots of applications).
At any time you can go to the Windows Store page or Apple Store page for ArtRage Vitae to re-install. So long as you're logged in with the same account you purchased with you can install ArtRage Vitae on as many computers as you like, as often as you like. You dont need to register with the ArtRage Members area, and you dont need to keep track of ArtRage serial numbers.
Here are the links to ArtRage Vitae in the Windows and Apple stores if you ever need to reinstall:
The Windows Store (if you’re using Microsoft Windows): ms-windows-store://pdp/?productid=9NJK057NFZCP
Or the Apple App store (if you’re using Apple MacOS): https://apps.apple.com/us/app/artrag...e/id1532816883

The information you gave only applies if you purchase ArtRage 6 (or earlier) in the ArtRage Store.
