I just learned something new today. It's a flavor of Windows called: Windows 7 N. It is Windows 7 "Not with the Media Player."
The implications of this special flavor is that when you run AutoCAD Civil 3D 2013 with Autodesk Storm & Sanitary Analysis 2013 installed, you will get this error:
Error 1904. VisioForge_Video_Capture_4.ocx failed to register.
You will need to manually install the Windows Media Player to get around this problem.
Thanks to Byron Morales for sharing this tidbit of information.
