No, it is because you don't have installed on your computer directx 9.0c, you can run directx 10 and directx 9.0c at the same time, I also have windows vista and chipset built-in, FPSC will run but you won't be able to get a lot of fps or use fullshader or too many lights because your computer will run really slow because of the video card. I had to update my video card and my video games jumped from 16 fps to 35 fps. Like I said, you will be able to run fpsc but it will run a little slower. Just make sure to install directx 9.0c then install fpsc, then, you put it in compatibility with windows XP and also like administrator. The directx that comes in the cd with fpsc will not install itself on your computer(it didn't do it for me), it will say, that you don't need directx because you already have the latest one running in your system. Try installing FPSC 9 free edition, if that one run it is possible that fpsc 10 runs too. I am not sure on that one. Good Luck.
