I have the game 18 wheels of steel convoy and it won't start up because prism3d will not start because it can not find the control.def file what do I need to do. "please help"!

The first thing to try is updating the driver for your graphics card and making sure that you are running the latest version of DirectX from Microsoft.

My graphics card has all its driver updates. And I have directx 9.0 where does the control.def file come from?

There is another thread on this site concerning this game.
It is HERE.

Please read through it and try the suggestions.

I have the 32 MB Intel 82815 Graphics Controller to what can I do.

Well, as mentioned on the other thread, the game needs a seperate graphics card and will not run with an Intel graphics controller.
The only thing you can do is invest in a graphics card, there is a wide range and are inexpensive.

OK thanks for your help.
