Running 'setup.exe' is normally sufficient. But if this fails to initiate the device, go to the device mangager (hold ALT and double click 'my computer') and look under 'sound and video controllers'. If you see exclamation marks listed, double click on them, select the DRIVER tab and then the UPDATE DRIVER button. Follow the wizard to update the driver, and let it know that you want to browse for a driver. Point it towards the driver folder that you have downloaded.
