Why am I unable to download a game on pc that I already own on Xbox digitally?

You should definitely try to ask for a refund if you're unable to get your save data onto the complete edition of the game.

oh no....then in that case I'm just going to ask for a refund. I read somewhere that sometimes the external HD isn't recognized so It tries to download the same copy of the game twice. I'll contact support and see what they say.

I may be mistaken but the complete edition is a different copy of the game. Your progress doesn't carry over sadly.

I hope it works out for you good luck

Hi Charlie! My name is Darhyl and I’d be more than happy to help you with your query.

I'm sorry you are experiencing this with your Fortnite game download. No worries, let me help you sort this out.

It's important to note that this is a public user-to-user community forum, and none of us here work for Microsoft.

I just want to confirm, does this happen to all of your games or just specifically to Fortnite?

Kindly try to perform the following workarounds:

1. Clear out your MAC address:

Settings > Network Settings > Advanced Settings > Alternate Mac Address > Clear it and the console should restart. It would definitely help if you could restart the internet router while the console is restarting.

2. Clear the local save for Fortnite and resync with the cloud. Here's how:

It’s possible that the local save for your game has become corrupted. If so, deleting the local save and re-syncing with the cloud might correct the problem.

First, delete the local save:

Press the Xbox button  to open the guide and then select My games & apps > See all > Games.
Highlight the game title, and then press the Menu button  on your controller.
Select Manage game and add-ons > Saved data.
Select Delete all to remove the local save of this game, then follow the prompts.

After you delete the local save, restart your Xbox:

Press and hold the Xbox button  in the center of your controller.
Select Restart console, then follow the prompts.

After you restart your Xbox, re-sync your saved games to the cloud. Your saved games are automatically stored in the cloud while you’re connected to the Xbox service.

Try installing the game again to see if re-syncing with the cloud corrected the game problem.

Note: When doing this step please make sure that you used to play this game online so that all your data is saved to the cloud.

3. In case the issue still persists, the next step would be to perform the Factory Reset keep my games and apps on your console. To do so you will need to follow the steps below to perform a reset on the Xbox:

Note: This will remove the profiles on your console, make sure that you remember the email and password to your account.

Press the Xbox button  to open the guide.
Select Profile & system > Settings > System > Console info.
Select Reset console.
On the Reset your console? screen, you'll see three options. Be sure to choose the Reset and keep my games & apps option so that you don’t lose any of your games and apps.

This will also help sync the data on your console properly. Once you're done, try to check if you will be able to download and launch Fortnite without any issues.

Thank you for your kindness and understanding! Please feel free to let me know if you need anything else.

Best Regards,
Darhyl
