Extract it to the desktop, it should work fine.

Did you extract 3D-Analyze onto the desktop? If not, do that and try again. Not sure why but it has to be on the desktop.

I downloaded 3D-Analyze for the sole purpose of playing Fallout 3 on my laptop. I had to mess around a bit, but I finally got it to run to where I can click "play", but it won't open the actual game. I'm [of course] opening it through 3D-Analyze and I've tried a **** ton of different combinations of boxes to see if anything works, but nothing does.
