It also says

"Setup will also determine whether it is necessary to install Direct X. You need to have DirectX 9.0b or higher installed in order to play Wings of War"

and later
"..The game will run only with graphics adapters supporting hardware T&L and texture compression ( eg nVidia GeForce and higher or ATI Radeon 7500 and higher) Please make sure that texture compression is enabled on your graphics driver settings"

Hope this helps.
