Error code: 0x80073d13 (Xbox Game Pass PC Beta)

I work on a shadow computer and i had the same problem and error.

I found a clear solution on another website.

It works for me!

The issue here is your disk format. GamePass games don't have to be installed on your C: drive, but they do need the following:

• NTFS formatted partition
• 4096 byte allocation unit size

Both of these requirements stem from the delta-update mechanism GamePass games use.  It relies on some low level features of NTFS to efficiently move data around on the drive during game updates. Changing the external disk to be NTFS / 4KB allocation size will allow you to move games there or set that disk as your default installation drive.

Ok, Do this to make it work....some of you out there are using Shadow....but this also applies if your hard drives are not configured correctly...hope this helps...it did for me. If you dont have shadow disregard the shadow stuff and just partition off a section on your hard-drive in the tutorial. Microsoft....get you team together and help your community out....this is shameful that you release this awesome app and leave people hanging like this.....COME ON! 

For those of you who have been running into issues installing Xbox Game Pass games on your Shadow and you're getting an error:

"For this game, choose a drive that's formatted as NTFS" or error code 0x80073D13

The issue is that your Shadow's C drive has been formatted with a cluster size (byte allocation size) of something other than 4k (mine is set to 16k). XGP games require that the drive/partition you want to install the game on has a byte allocation size of 4k (not sure why Shadow is setting it to such a large value). Good news is that there's a workaround that doesn't require reformatting or rebuilding of your Shadow PC.

(Caution: this is somewhat advanced, so if there's anything you absolutely cannot lose on your Shadow PC and you're not comfortable with making disk partition changes or you haven't done it before, contact Shadow Support instead just in case).

The following steps will create a new partition (drive D) on your Shadow PC by borrowing space from its C drive. These instructions assume that you only have one drive (C) currently.

1. Open the Disk Management app by pressing WIN-R and entering "diskmgmt.msc", then hitting Enter.
2. Right-click the C drive in the grid at the top and select "Shrink Volume...".
3. In the window that appears, choose the amount of space you want to shrink the C drive by. This will be the space you will allocate to a new D drive later.
   1. DO NOT choose the entire amount displayed in the "Size of available shrink space in MB" field. You want to leave Windows some breathing room. Enter a number that's half of the available shrink space to be safe, as long as it's enough to fit the game(s) you want to install.
4. Click "Shrink" and after a moment your C drive will be a bit smaller and you'll notice a new "Unallocated" section of the "Disk 0" graph near the bottom.
5. Right-click on the "Unallocated" space at the bottom right and select "New Simple Volume...".
6. This will go through the process of formatting the unallocated space as drive D. Feel free to customize anything... just make sure that the "Allocation size unit" is either set to "Default" or "4k". However, it is safe to just "next" your way through the wizard.
7. You now have a D drive. This will be where you'll install the XGP games:
8. In the Xbox app, click your profile icon at the top and select "Settings".
9. Click "General" on the left.
10. In the "Drive selection" section on the right, click the "(C:)" dropdown and select "(D:).
11. Try installing a game. It should now be successful.

Solved since last update.

Thx MS

Exact same problem here I had a different error code, restarted and now have the same as above, please fix for allowing installs elsewhere.
