Installation error on Windows 7 64bit w/ Quadro FX 3700M

I am installing the CUDA driver on Windows 7 64bit on a system that has Quadro FX 3700M (Lenovo machine) graphics card. I downloaded this from the NVIDIA CUDA download site. Right after the installation starts, I get following error:

The NVIDIA Setup program could not locate any drivers that are compatible with your current hardware. Setup will now exit.

Any idea what is going wrong here? How to avoid this error?

Thanks, Kaarigar
