I had this problem on 08-01-2016 and this was my fix.
The problem was Microsoft automatically downloaded Office 365 (beta) version which clearly has some major isuses.
Below is a comparison on what my work computer had and what my home computer has on it currently.
Work PC Version
Home PC Version
The fix was to go backwards so we ran these commands as administrator from the command prompt and typed in the following commands.
cd %programfiles%\Common Files\Microsoft Shared\ClickToRun
officec2rclient.exe /update user updatetoversion=16.0.6965.2058
