When start the game it says "medal of honor airborne requires Physx to be installed in order to run properly. See the readme file for instructions on how to install Physx".

If you got this message when you click on game to play, do this.

1- Go to Control Panel

2- Select Programs and Features

3- Search "Nvidia Physx"

4- Click on it

Now you can play Medal of Honor Airborne. Later if you want update your Nvidia Physx, just remove the version you have installed, and install a new one. No problems with that modification.
