Go to the Security Tab, and add, if it is missing,k with full right: ALL APPLICATION PACKAGES. If that doesn't help, go to C:\Users\AppData\Local\, right-click on "Packages" and select Properties. If that doesn't help, not even an uninstall, restart and re-install: Run the Windows App Troubleshooter: (Start > Settings (gear icon) > Update & Security > Troubleshoot > Windows Store App, and follow the wizard.
