I don't know with Vista, but I couldn't run it with Office 2007 in XP. In the end, I went back to Word 2003 and had no more problems. I found a way to have both Word 2003 and 2007 in the same system that I explained in the following thread
http://www.english-spanish-translato...lp-please.html (in XP, not Vista)
I couldn't have the time to try it in Vista yet, but everytihing I've read about it is not encouraging. Any news, I'll let you know.
