I can't install my Game Pass games to the D drive anymore because it was "old device"?

Since you have gamepass and if the games are still on gamepass just go download them again.

That's exactly what I want to do.

I can't download them, though, because I installed my old hard drive in a new computer. The app keeps telling me I can't install the games on the old drive, because data from another device is still installed, but I also can't uninstall the old data.

Games will intall onto my C drive (the drive that has WIndows installed onto it), but now I can't choose to install games onto my D or E drive, because I deleted the WPsystem folders.

As I understand it, it is not about where the game is installed but where it is unlocked for your account.

That means I can now always install Limbo immediately on drive D, because it was recently unlocked for my account.

But a new game installed on D fails. You can not start it. If you install the game on C first, it will be decrypted and can be launched.

I think there is a bug after the installation, which does not decrypt all files. That's why you can't move the game anymore.

This is a bug that Microsoft needs to fix.

so u are telling me that i can't clone an HD with Xbox pass game on it? Because i really can't do nothing anymore with my xbox app, i can't install game on that HD nor delete the old one. The only solution that i've found is to force access on that folder
and manually delete the game, hoping that, then, windows can recognize that folder as empty and allow me to install over there.

Maybe that's a problem Windows need to solve

It sounds like you are having trouble installing games from the Xbox Game Pass on your D drive.

Make sure that you have enough free space on your D drive to install the games.

Check if there are any updates available for the Xbox Game Pass app and install them.

Try resetting the Xbox Game Pass app:

On your Xbox One console, go to "My games and apps"

Navigate to the Xbox Game Pass app and press the "Menu" button on your controller.

Select "Manage app" and then "Reset".

Confirm the reset and try installing the game again.

If none of the above steps help, you can try uninstalling and reinstalling the Xbox Game Pass app. Make sure to select the D drive as the installation location when you reinstall it.
