Cannot install on Windows 10

I purchased Forza Motorsport 7 Ultimate edition, but when I attempt to download and install, the only option I have is “install to Xbox One”. I don’t own an xbox… I have searched everywhere on the internet, and every fix I tried…failed. Why does Microsoft have to make this so difficult? Does anybody have this working or did I blow $90.00?

Does your pc meet minimum requirements
Have you fully updated windows 10 to the latest update
