A good place to start is determining your directx version, or if you have it installed at all.
Start menu -> Run -> dxdiag.exe
If it doesn't run, google directx and install it. If it runs, verify version. If it's lower than 8.1, google directx and install it.
I mean, hell, error message tells you as much. I have a feeling that if you couldn't understand it, this post won't be much help either, because of language barrier.
