Game pass games won't install to my pc.

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today despite this Jake

May I know if you already tried everything from this article?
https://support.xbox.com/en-US/help/games-apps/...

Or most specific to the Gaming services part:

Press Windows key + X and then select Windows PowerShell (Admin).

Type or copy / past the following command and press Enter:

Get-AppxPackage *gamingservices* -allusers | remove-appxpackage -allusers

Restart the PC and Open the Xbox application.

A blue notification with the following message is going to appear at the bottom:
"This app needs an extra component. Gaming Services is needed for playing some games. Administrator approval required. Install"

Select Install to reinstall Gaming Services, once installed check again

How you fix it?

The problem is the Game Pass App on Windows even if Microsoft won't admit it.

If you use the Game Pass App on your phone, it will allow you to "remote" install the games on your PC. Just make sure to select PC games tab otherwise it will assume you're trying to install on an Xbox console.

If, in your history area, it will only let you install to Xbox and not PC, then it;s the Xbox version....I have the MCC on my Xbox and my PC Store won't allow me to install it naturally. As it sounds like you bought it from a 3rd party, you'd need to go back to them and get a refund or exchange.

An alternative if you only want to play the game once is to maybe subscribe to the PC Game Pass for a month or 2 as Reach is included within the GP version of the MCC. The PC Game Pass is still £1 (depends on local currency) for the first month

That could either be Game Pass Core or PC Game Pass. If it's Core, it won't work on PC.

You need to install the Game Pass for PC app to install games from Game Pass on your PC.

Hope that makes sense
