The general advice is to avoid all the sites that promise you drivers when you Google for this problem.
Plug the camera in and go to Control Panel>System>Device manager and highlight the device, then right click it and go to Properties. Click the Details tab and scroll to HardwareID. take the four characters which follow VEN for Vendor and the four after DEV for Device.
Go to http://www.pcidatabse.com and input those details in the Vendor and Device boxes and hit Enter. You should be guided to the manufacturer and their own site - always the safest place to download a driver.
