Did you find a resolution to this?  It sounds like after the Microsoft update it broke this connection and export process.  Quickbooks need to get with their developers and get this fixed.  Every operating system will have security patches and updates that QB needs to plan, program, and implement after these patches are released.  After wasting hours on the phone with QB tech support, they say its not their issue but a Microsoft problem. 
I have:

Uninstalled Microsoft Office
Uninstalled QB
Updated all security patches for Windows 10. 
Cleaned Temp Files, cleaned Registry

Reinstalled Quickbooks & Office
Installed all patches / updates to both software

Still no go.  
Whats the deal QB?  Do I sense SAGE in my future along with all my clients we support?
