Unable to update game

Opened the battle.net launcher to see and update pending for retail, so i click on update, only to get an error message saying “looks like something broke, please restart battle.net and try again”

I’ve done this numerous times, running a scan and repair doesn’t work as that breaks about 50% of the way through too.

Anyone else having this issue? Only happening with live retail, non of the other versions seem effected.
