Greetings Exile,
Thank you for getting back to us. Since a fresh reinstall is not forcing the app to pull the missing files please suggest the following steps to your friends:
- Repair & restore the gaming services app. You can find this option by following:
Windows settings > Apps > Gaming services app > Select advanced options > Select repair and after it > restore.
After these steps, please open the app and give it another try. Let us know if this does the trick or not. We will continue to try to assist you.
