I know you said you have 64-bit Office 365 installed. Are you absolutely sure of that?
I know this happened to me when I accidentally installed the 32-bit on my 64-bit box.
To verify if you go into the start menu and see where it's pointing, your MSAccess.exe should in
C:\Program Files\Microsoft Office\....
(if it's in C:\Program Files (x86) then it's the 32-bit version)
Mine happens to be in
C:\Program Files\Microsoft Office\root\Office16\msaccess.exe
Hope this helps,
Regina
