How do I add a watermark to my video in Windows Movie Maker?

I downloaded the zip file and went to "C:\Program Files\Movie Maker\Shared\". The folder AddOnTFX wasn't there so I made it myself. I extracted the two files into that folder and restarted windows movie maker but when I go to change animation settings, the option watermark isn't there.
