Hello,

Just to clarify you are talking about PC? If so are you on windows 10 or windows 11 and are you using the Xbox app or the Game Bar for parties?

Thanks,

The companion app is for consoles

You need to buy it on the xbox app on your windows 10

By using the Xbox console companion app you queued the Xbox game not the pc game

And fable 2 isn't available per say on Windows 10 but there is one offical way to play it on Windows 10

You need to update to the recent windows 10 anniversary update if it's available to you in your region

It's varies region by region as ita a phased release since the Xbox 20th anniversary not long ago

Once you have it you need to download the xbox play app which lets you play non windows supported xbox games like fable 2

And yes it is ms offical xbox app to play 360 games
