​I bought a Forza Horizon 3 game disc for XBox One and would like to install it also on a ...

You would need to purchase the game from the Windows Store. The disc will only work on the One.

Only the digital version of Forza Horizon 3, bought on Xbox One, would allow you to also download the game on Windows 10. It is a Play Anywhere title, meaning that when bought (digitally) on one platform it's accessible on both.

This offer does not extend to disc-based copies of the game.

Hope this helps.

Just to get that sure for me. On Gamestar.de and Golem.de I read, that

" Das Play-Anywhere-Programm unterstützt ausschließlich digital erworbene Spiele. Wenn Sie also beispielsweise eine Disc-Version von Forza Horizon 3 für die Xbox One kaufen, können Sie sie nicht am PC spielen."

It says, that "The Play-Anywhere-Programm only supports digital bought Games. If you buy the Disc Version of Forza Horizon 3 for Xbox One for example, you can't play it on PC"

So just to get sure, If i buy the Xbox One Disc Vsion, I can activate and Play it on PC without haveing an Xbox. And gamestar.de and golem.de statet that wrong?

Purchased new Call of duty xbox one bundle tooks hours to install game.After it was done installed lords of fallen game disc normally.After that tried to install Forza Horizon 2 and Battlefield 4 and the installation would keep stopping and not installing.

Thanks for your help, my issue has been resolved! I didn't know you could install games from a disc remotely, I thought it was only available for digital purchases. Apart from RDR2, I also installed Forza Horizon 3 which was also damaged.
