Can't start Office 356 applications

[mta]

well, I'm tapping out at this point.

that's me exhausted of ideas to try.

if it was mine, after doing all the above suggestions without success, it's now time to nuke it from space.

big hammer to hit it with for sure - but last resorts usually are.

 

hopefully someone can chime in with something myself or @hazelnut hasn't thought of.

 

and just to learn from a hard lesson to future proofing your system, start doing system image backups - not just data backups of your pics, docs, emails etc, but of the PC as a whole, at the Windows level.

they're like a snapshot in time of your PC - data, software, settings, everything.

an excellent, and free, one is Macrium Reflect.

do yourself a favour and make it your new nest friend.
