DOS Games Discussion

Have installed Jetfighter Full Burn to c drive & it is mounted correctly in dosbox. When running dir, all files appear including the 2 required exe files. When selecting setup.exe it sets up the game basics (sound, joystick options, music) and allows to save and exit. I am then taken back to dos. The exe to run the game is FB.Exe, but each time I select it, I am left in dos with the curser flashing at C:\>. Any ideas?

Running Windows 8.1 64 bit.
