well, either you computer doesn't have the req processor stuff, and i think you might need DirectX SDK if you downloaded the setup after April, SDK can be found in the microsoft downlaody thing online, just search for DirectX SDK, the file is nearly 400mb

or else some of the files are corrupted or the destination of the shortcut is incorrect, or maybe you're not clikin the right thing? hmm computers, endless error possibilities

or maybe its your video card, could be alotta things
