I try to run ballistics ...

With WinXP-SP1 I get the error "Program to big to fit in memory" (dos window) when i try to run setup from cd.
With Win98SE I get the error "not a valid win32 app" (win alert).

So I tried dosbox in xp ... When i try to run setup (to install the game, what else) nothing happens.
The extensions are shortened on the install disc (ex_, tx_, etc), so i tried copying the complete disc to hdd, and rename ballistics.ex_ to .exe.
When i try to run that file, i get this "illegal call 7" error, and dosbox closes ...

So, why doesn't setup do a thing, and why do i get that illegal call error?

tia!
