Hi Villads Borup,
Since Gaming Services reports OK, the drive has sufficient free space, and sfc /scannow found no integrity issues, I would avoid reinstalling Gaming Services again for now.
Instead, please try the built-in Drive compatibility tool:
- Open the Xbox app.
- Select your profile picture > Support.
- Select Drive compatibility tool.
- Follow the prompts, then restart Windows and test the installation again.
If the problem remains, also run Profile picture > Support > Gaming Services Repair Tool > Start Troubleshooting. This is Microsoft's dedicated tool for Gaming Services installation and related Xbox app issues.
If neither tool resolves the folder detection issue, I’d recommend contacting Xbox Support, as further investigation may be needed rather than repeatedly reinstalling the same components.
I hope this helps get the installation location recognized again.
