Trying to register a game I bought on Steam

The only thing I can think of to try is to enter your serial/product key into Steam. There's an option to add games to your steam library, then enter the product key. If that works, you would be able to register your serial key with Steam, then digitally
install it through there.

Just thinking it would have an option to register the game so it can be played on different devices, but I guess it's only limited to just having it on old and next gen consoles. But to be honest, portal 2 did it. If you bought the game you can register it and play it with the pc on steam. So it wasn't out of the realm of possibility. And since Microsoft is also based in the pc world just wishful thinking.

I have same problem. I and my friend bought game on steam. When we try to create convoy with our gamepass pc friend we having crash as steam users.

would love to say nothing has worked but not to worry i bought the game on steam thank you for trying to help me

I've bought the game on Steam. However, in-game it makes me use GFWL. I can still access Steam in-game tho
