I can't download games

I would contact xbox support.

Are you reset you network?

Hi,

I would personally make sure the game you are trying to download is backwards conpatable you can check here.

Have you tried stoping the installation completely and restarting it? If you have and it is still not working try restarting your router and hard restarting your xbox by holding down the power for 10 seconds and once it shuts down leave it off for 45 seconds
and then power it back on.

The last stage is to be done very carefully to ensure you don’t make any accidents.
Go to settings, console info, reset console, reset console and keep my games & apps.

You will need to go through the whole proccess of having to setup your xbox again but do not be scared. Once this last step is completely
VERY CAREFULLY this should stop this from happening.

Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you with your concern.

If I may ask, what is the exact error or issue that you're experiencing whenever you're trying to download GTA V? Is it asking you to purchase it again?

Hey, that's nice to hear!
I reply only to the refund part due to I saw your recent edit.

I'm glad to hear that you're able to play the game!
Take care buddy!
