Have tried both with Battle Net Launcher (refunded already) and now Steam.  After install, when trying to launch the game it will sit showing "Running Install Script ("GamingRepair.PROGRAM") for almost 5 minutes, then go away and say that the game is launched but nothing shows.  Going into Task Manager shows BootStrapPackagedGame and TheOuterworlds2 as background processes that are using no  cpu.  Already ran full file scan.  

Event Viewer shows a WER report for XboxPCGamingRepairFailed (full text attached).

I don't think this is a issue with Battle Net Launcher, but instead the Gaming Services Repair Tool thats included with the game.

Likely cause : A corrupted Windows or partially-installed Gaming Services package or a Store/Xbox framework issue blocked the automated repair.

1 : Reset the Store deployment cache
Press Win+R (or Command Prompt Terminal as Admin) → run: wsreset.exe
When the Store opens, close it.

2 : Repair / Reset the Xbox & Microsoft Store apps

Settings → Apps → Installed apps 
Xbox → Advanced options → Repair (then Reset if needed).
Gaming Services → Advanced options → Repair (then Reset if needed).

System → System components
Microsoft Store → Advanced options → Repair (then Reset if needed).

3 : Reinstall Gaming Services (clean)

Open Windows PowerShell (Admin) and run:

get-appxpackage *gamingservices* -allusers | remove-appxpackage -allusers
start ms-windows-store://pdp/?productid=9MWPM2CQNLHN

In the Store page that opens, install Gaming Services, then reboot.

4: Verify Gaming services are running

Open services.msc and ensure Gaming Services and Gaming Services Net are Running and Startup type: Automatic (Delayed Start).

5: Repair system files (in case 0x8000FFFF is OS-side)

Open Command Prompt (Admin):

sfc /scannow
dism /online /cleanup-image /restorehealth

Reboot.

6: Other things to consider

Make sure you are signed into the Microsoft Store and Xbox app with the same account.

Temporarily disable third-party AV or other software that can block or interfere with the game

Make sure you are Administrator
