Files can also be installed from outside the Store, is it possible to add a link to the download page? https://files.community/download

Improved the startup experience when the Windows App Runtime is missing or corrupted. Previously the app would silently terminate showing only a brief loading cursor with no feedback. The improvement catches the COM registration failure ('REGDB_E_CLASSNOTREG') on the first Windows App Runtime call, shows a user-facing error dialog and rethrows a descriptive exception so the failure is recorded in Windows Event Viewer.
