SWAT3

[CO791]

I have the latest patch and crack for SWAT3 multiplayer.however some of the addons cannot be installed because it does not detect the swat.exe file. The game does work however if I go to that file and manually click on it{swat.exe}.
Is there something else I have to do to this exe file for the system to detect it ?Also if I try to start the game through "program files" it cannot find the exe file for swat3. Any ideas?
