USB Keyboard Driver problems

Hi,

I am trying to use my Logitech keyboard on my laptop (which is running
vista) and when i plug in the USB it tells me that windows cannot locate the
driver.

I have spoken with the logitech support team and I have downloaded setpoint
but the device is still not working.

I took the keyboard to work and plugged it into my work computer as well as
my other PC at home and the keyboard worked fine. 1 computer was using XP and
the other was vista.

Can anyone help me with this, it is really frustrating.
