Xbox/Microsoft Store not letting me install Xbox game pass game to my External Drive

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 Armorman1

Your external drive is already formatted as NTFS? Please double check that opening file explorer > my computer > right click on the drive > properties > next to file system

I ask this because most of the newer games has this requirement

If this is not a USB – C external drive, it is likely not fast enough to play games from as well

All of my Microsoft and Xbox games are downloaded on my external drive including the previous Horizon, which is Forza Horizon 4. I changed where new apps are stored when downloaded from the Microsoft store to my external drive but it still wont download Forza Horizon 5 to my external drive. On the Xbox app it wont show my external drive as an option to download to. I am able to download any game from the Microsoft store and Xbox app to my external drive except Forza Horizon 5.

Hi, sorry for that issue, the problem is the external hard drive, for some reason (I don't know why), the games that require Administrator approval have issue on external drive.

Thanks for the answer. External hard drive it is not the problem in my case. While trying to find a solution to this Xbox Game pass for PC / Windows Store error I did reinstall Windows 10 on my iMac's internal hard drive. The problem with error 0x8007001f
persists even when Windows 10 is installed on the internal hard drive.

uild on external macbook hard drive/dual boot) Did you figure any solution to this? i can install other games fine but when i try to install halo mcc it errors out at 4.8%

... I suspect the "problem" might be that my Windows 10 system resides on an external hard disk which somehow messes up the installation process for "Administrator approval required for installation" games.

I have similar issues with apps and external storage.

It seems that for whatever reason, external drives aren't "trusted" as much as an internal system drive.

How is the external drive connected? Via USB, or is it an external SATA connector? You might coax the system into believing it's an internal drive, if you use an external SATA connector.

If you actually managed to install Windows on an USB drive (and it's not an official Windows To Go install), that might really be the problem.

The setup is an iMac 2019 with external Thunderbolt 3 SSD drive with Windows 10 Pro installed on it specifically for gaming needs. The problem with Xbox Games Pass for PC is the first (serious, mysterious) problem I have with this setup. Steam, Epic, GoG
- every other online gaming store works as it should and I can play pretty much any game I want, except for the ones available on the Games Pass for PC. I find it somewhat ironic.
