system.runtime.interopservices.comexception (0x800a1066) command failed Windows 8.1

I have a application that opens a MS Word Document Template and populates bookmark data from the application into the Word Document Template.  The program works without errors on Windows 7 machines and used to work on the Windows 8.1 machines but starting last week I started getting the error: system.runtime.interopservices.comexception (0x800a1066) command failed on the Windows 8.1 machines.  I uninstalled the updates that were applied last week but it didn't help.

I've tried various solutions that have been listed through out the internet all to no avail.  The application is using .Net 4.0 libraries and I'm not sure bumping it up to .Net 4.5 will make any difference.  Any Suggestions?

Found a solution.  Microsoft dropped support for Office 2003 on April 8th 2015.  Changed the Document Template from a .DOT file format (Office 2003) to a newer .DOTX file format and recompiled program to open newer document and it now works.
