The KB article applies to Word (no matter which operating system you're using), which is made clear in the title: "Troubleshoot problems that occur when you start or use Word 2010, 2007, or 2003."

Unfortunately, add-ins come from a variety of sources, so the fact that the installation is fresh doesn't make much difference.

What have you exactly tried to do? What happens when you try opening Normal as a document? Is there an error message?
