Install from microsoft store not working

Have you tried a push install from the Microsoft store page for the game, or using Microsoft Store on a PC and select install to device?

Thanks.

Tried that and it still doesn't work. I not cannot install anything from Microsoft Store. For example I tried installing Minesweeper and kept getting error 0x80070015 again.

This may be an issue with the Store itself and not the title. If you have a PC with Windows 10, access the Microsoft Store from there and search for the demo. Then install it on your Xbox from there. If not, try doing the same from the Store on the Xbox
mobile app. If this still doesn't work, then contact Xbox support.

I was able to install from the Microsoft Store app. Search for "Xbox (Beta)" or follow this link:

https://www.microsoft.com/store/productId/9MV0B5HZVK9Z

Located in Germany, even using a Windows 10 Professional Installation done via the latest en-us .iso and fully updated, neither the standard download of the Xbox (Beta) Installer, nor searching, aquiring and installing from the Microsoft Store did provide
a working Installation.

In case of the non-Microsoft-Store separate download offered, the Installer hangs, seemingly when normally requiring granting administrative rights. Installation via the standard (Germany/de-de) Microsoft Store Release did not work.

Using the link you provided [ https://www.microsoft.com/store/productId/9MV0B5HZVK9Z ] and choosing to use the United States version of the Microsoft Store and not to switch to the (if located in Germany) normally used
version of the Store for Germany, opens the description.

Then clicking Install in the upper right to aquire the Xbox (beta) App asks to open the link in the locally installed Miocrosoft Store of Windows 10.

Done this way the Xbox (Beta) App für Windows 10 installs without an issue after granting administrative rights. Once open a notification informs that the Gaming service is missing and has to be installed, which requires
administrative rights.

A click on the "Install"-link at the end of the notification-line installs the missing service and the Xbox (Beta) App is fully usable as intended.

Thanks, for sharing the information and the link, to nickv2002!

The fix I found for a new build I was working on was to install
Gaming Services from the Microsoft Store:

It seems that it may not download/update by default.
