Xbox (BETA) Installer error 0x803FB005

So this morning after letting a few games download over night, (no reboot), I opened the store again and clicked the same failed download and it instantly downloaded, then updated immediately after installing with no errors.

Possibly something on the far end? Appears all good to go now.

Hi Smeagol251!

You can try to do as indicated in this topic: https://answers.microsoft.com/en-us/windows/forum/windows_10-update/erro-0x80070005-como-resolver/688be9c4-9246-4e4f-9b79-424f8e93269f

I sincerely hope it helps you"

I started the app as an administrator. It worked.

I had the same issue, resolved it by downloading it directly from Microsoft Store.

Hit the windows key, then type "Microsoft Store" - log in, then search "Xbox Beta" in the search bar.

Try to download it through there.

Worked for me, hope it helps you!

Hi Smeagol, I may have a solution for you, or at least a workaround.

I couldn't get the app to install either and I received the same error message. However, if you try typing xbox into the Search field in the taskbar you should find an app called Xbox Console Companion. I believe it comes preinstalled with Windows 10.

After loading up the Console Companion and logging into it with my xbox live password, I was able to browse and install games that come with the Xbox Game Pass.

I hope this helps,
