Failed to open document

[bob]

I upgraded:-
from Windows 7 to Windows 10
from Office 2013 to Office 2016 (although it claims to be Microsoft Office 365 Pro-Plus)
and upgraded EaDOCX to 3.9.5.7 from 3.7.3.0.

Now it doesn’t work and I can’t eve open any document I created in it within EADocX.
Outside they open fine.
