cuda problem on vista 32

hi everybody
im new to cuda and all this and i tried to install it on my laptop “MSI ex623” it has windows vista 32
i tried to install the drivers from nvidia website directly more than 4 times and tried to install the cuda drivers many times too but i get the same error message

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

i have googled alot and read many posts in this forum and other ones yet i couldnt find a solution, i hope i can get a solution from you guys

thanks in advance
