I would check to see if this is a DOS based application, if so the solution above has no bearing. I would try to open a DOS window, and go to the location of the program and run it from there. If it is a NIC program it is most likly DOS based. In NT you can get a DOS window by typing CMD in the Start/RUN menu. once there use that old Command line navigation and find the executable for the program.... type it in and see where it takes you.
Good Luck,
