FSX Acceleration Installation Problem - Shader Model & Graphics

When I try to install FSX: Acceleration, it says "Microsoft Flight Simulator X: Acceleration requires a video card supporting Shader Model 1.1 or later," then the installation exits. I need a fix for this please!! Please include links and steps for this to be easy as possible.
