Probably because it's looking for a different process than what you're running.

Here's a thought, run it for the game version it's for. Be it iw5m, steam or teknomw3. Then you shouldn't have a problem.
If you use iw5mp.exe, rename it to iw5m.dat and run this. Or tell your friend update it for the executable you are using.
