Hey I can send you guys the .exe you need if you want. I was fortunate enough recently to stumble upon a site that had it.
You need to install the official patch and update GP3 to GP3 v1.13 before you can do anything else though. www.download.com/Grand-Prix-3-patch-1-13/3000-7521_4-10236469.html
There are still some sites out there who have old stuff:

www.grand-prix.4players.de] (choose the gp3 2000 side, and when looking for downloads look in both gp3 and gp3 2000 as most of the downloads apply to both games)
