My webcam is not working

When i plug my usb microsoft vx 3000 webcam into a working usb port on my desktop computer a little box pops up on the lower right of the screen saying my computer is detecting a new usb camera device. then a box pops up saying the device is not installed and may not function. sure enough the device wont function so i unplug it and go to the website to download the newest drivers. when i finish downloading the drivers i start to install them, and around half way through the process a box pops up saying there was an unexpected error and the installation was failed. i have tried this many different times with a couple of different versions of the software and i get the same result every time.
