Based on what you mentioned and error code that might be the issue, of course you can spam redownloading it and hope it eventually goes through as I did. Unfortuently it tends to be a reoccuring issue with Windows after every update. Just recently I lost access to my RealTek HD Audio Manager for no reason. Re-installing it is absurdly annoying, Windows 10 is greeeeeeeat…
Ah, I forgot… the data cap became a thing. Shoot. Yeah, repair systems or giving permission would be your next best step. Wish I was more in tune with Windows 10, but I hate everything about it so I tend to stay away. Hopefully the support guy knows his stuff and doesn’t send you on a wild goose chase.
