 1. When building this I had the Microsoft.Office.Interop.Word 12.0 (Word 2007) library referenced from the project. The easiest way to meet this requirement is to install some recent version of Office, but any version of the Microsoft.Office.Interop.Word library that natively handles the .docx format should work.
 2. I had the very useful Html Agility Pack version 1.4.6 library referenced as well. I was using .NET 4.0 and the 4.0 version of the library.
