Vista 64 bit video drivers.... installation problems...please help.

[mainman134]

running system o/s vista 64 bit. Downloaded USB video drivers from software page but when installing i get error saying "b][/b] COULD NOT COMMUNICATE  TO THE  NETWORK SERVER ERROR 3"  "404 NOT FOUND". I also get the same message when trying to install the wireless remote drivers. Why do i get this error message and how do i install the drivers. All security sofware has been disabled before trying to download or install but still get the same message. Any one with suggestions on this would be greatly appreciated if you could share them with me. Thanks.
