PC Version Not Installing

So I own the xbox one version and am unable to figure out how to install it on windows, as its asking me to rebuy it. Thats something that shouldn’t be asking since I already own the game. Same thing for State of Decay 2, I own it on xbox and was easily able to click Install on windows. Is there something wrong with the windows store or does GenZ just not work on PC?

generation zero isent a part of the buy one , play on both pc and Xbox thing. so if you want to play it for pc you will have to rebuy it, but state of decay is, and that is mostly becuse its a microsoft exklusive,

Needs to be a “Play Anywhere” title which are almost always titles from Microsofts own development houses

how can u argue with that
