When does it crash? Does the opening intro movie play, and then crashes on the menu? Or does it crash when you fly?

IF, it crashes just after the intro movie, try this:

Try to run the game in window by changing the shortcut's value to:
[ "C:\Program Files (x86)\GOG.com\Red Baron Pack\Red Baron 3D\Baron.exe" -window ]

This will put your menu in Windowed mode (a little hard to read unfortunately), if you have a Glide Wrapper added, you can then change the graphics to Glide. The you should be able to remove the -window from the short cut. Your Menu will remained windowed, but the game should play in Full Screen Glide.

If it crashes again after removing the -window from the shortcut, add it back and just remember to change the game to Glide every time you play.
