Hi, I bought the forza horizon 2 day one deluxe edition digital edtion and began to download it, right now it’s been 2 hours and it’s 20%? With games like fifa 15 that took about an hour? Why is it taking so long?
Perhaps your console lost its internet connection for a moment and now the install is frozen?
Because you are installing and not in the middle of actual gameplay, I would go ahead and restart the console and reinitiate the install. If your console is currently running wirelessly, I suggest you plug an Ethernet cable into it, if you can.
And ALWAYS wait untill its 100% installed,don’t start when it says ready to play
Alright mate, I’m new to xbox one an forza horizon 2, Totally loving it too! I had the same problem an the best way i found out to install all my games faster was to disconnect the xbox from the internet by pulling the ethernet cable out or disconnecting the wifi and it installed much faster! hope this helps 
You need internet for digital version.
I did see he said that, but he also mentioned installing other games in general, just saying how i got my games to install faster an thought it may help him
