--- Comment #1 from ToastyBug cemer99797@isorax.com --- I accidentally added the "`file` command" text in the middle of the GUI error message text, it should read:
`file` command info for: jkdemo.exe PE32 executable (GUI) Intel 80386, for MS Windows
The jedi.exe file is a launcher GUI which works fine, but when clicking "Play Jedi Knight Demo" it fails with the error:
Unable to start the Jedi Knight Demo game program. Try running JK.EXE where you installed the Demo directly. Also make sure you have the latest DirectX drivers installed on your system.
