Train, that looks like the newest release (R2007b) of the professional version. I can only afford the student version, which is R2007a.

I don't see anything there to indicate whether or not it would work. And their website doesn't have an email address, I'd have to call. How annoying. I'm going to do a search online and see if anyone else has installed it on a x64 PC.

Thanks for looking into it, guys.
