I am having a problem opening a Microsoft Access database accdb file on my D: drive. It was working fine until recently when I upgraded to Windows10/Office 2016. Now all I get is : "File permission denied".
Bizarrely all the other Access databases in the same folder are completely accessible - apart from this single one.

I have tried changing the security permissions, changing ownership, logging on as Administrator - nothing seems to work.

The only thing I can think of is that on Windows 7 my user account was just "Nick" and now on Windows 10 it is "Nick B" with an email address associated with it.

Any help would be greatly appreciated
