nForce drivers won't install..

I downloaded the 2.41 drivers, but all it does is extract the files to a folder. I also tried running setup.exe from that folder, but it didn't seem to do anything either. Is this what is supposed to happen? No confirmation of installation?

I'm running Windows XP Pro and just installed SP1 today before I tried to install the nForce drivers.

download the latest ones again from nvidia... and start again

Nope, didn't work. I went ahead and updated the drivers manually
