CUDA toolkit installation for nVidia NVS 4200M


I have been trying to install CUDA toolkit 5.0 on my Lenovo T420 laptop with an intel integrated HD graphics card and an additional CUDA capable nVidia NVS 4200M graphics card. Upon installing the toolkit, during driver intallation I get the message that the installer could not find any compatible hardware. I am unable to understand as to what the problem might be. Can anyone please help and indicate how I can resolve this problem? Thanks.


Can you please install the latest driver from Then install CUDA toolkit without driver.
