I was attempting to install a game from Windows Store.
I changed the App storage location from C: to D: in 'Settings - Storage', as the game requires at least 29GiB diskspace.
Then the store wouldn't allow me to install any app with an error code '0x80073CF9'.
If I change it back to C: , everything goes just fine.
I got UAC enabled, 'AppReadiness' and 'AUInstallAgent' folders just in the place where they should be, I've tried Store App Diagnostic Program, I've checked the system language and location settings and they are also fine. But I still got this annoying error code.
Would somebody please help?
