.NET MS Interop Word - COM Class Factory Error

I am developing a .NET 2012 application and using Microsoft.Interop.Word. When my code gets to the sample code below it breaks in the Initialize method:

public class eobPrintBatch
{
    private Microsoft.Office.Interop.Word.Application wApp;

    private void Initialize()
    {
        wApp = new Microsoft.Office.Interop.Word.Application();  //Breaks here
    }
}

Open in new window

The error I am receiving is:

{"Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80080005."}

Any ideas?

Are you using the Microsoft Primary Interop Assemblies?

Basic info on PIA's:
http://msdn.microsoft.com/en-us/library/aax7sdch(v=vs.110).aspx

More information on Office PIA's:
http://msdn.microsoft.com/en-us/library/15s06t57.aspx

My best guess on this is that the .NET application is trying to load the appropriate Office COM object and unable to find it. You need to make sure you have the correct PIA's installed and properly "configured" to work with the correct version of Office on that system.

I removed the Interop and re-added it. Now I'm receiving

Now its back to its original error:
