Installing a game

Hello Megan,

Thank you for keeping us updated. Is this game a digital download, or a disc game? If it is a disc game, the disc could be faulty if used. Let us know this detail and we will do our best to help you out.

I would also test out your console to see if it is capable of completing downloads. Cancel the download for the cars game. You can then try downloading a demo, or a free game like fortnite.

Curious, how long have you let it sit at 40%? I've had games do this occassionally, and I'll see it sitting still when downloading and not progressing. I've honestly just left it and did something else, and came back later (maybe a half hour) and then
it would be moving a little again. I'm not sure if maybe the specific file it's downloading at that time might be larger or how it works, but I've done that before. I would let it sit for a little bit and see if it moves, but if it's not moving after 30-60
minutes then yes try more troubleshooting. Good luck!

It has a notification come up saying installation has stopped.

A hard reset of the console can fix the problem. Hold the power button until it turns off completely then try again.

It took two tries but I think it's working now! Thanks
