Wireless Xbox 360 Controller Receiver For Windows Not Detecting/Working

I purchased the Xbox 360 Wireless Controller Receiver For Windows and it is not working. I am running Windows 7 64-bit on a Sony Vaio VGN-NW225F laptop. I navigated to the correct place on Microsoft's website and downloaded the appropriate Windows 7 64-bit software for my receiver. It was an exe file and it installed correctly, or at least it said it did. This leads me to believe it is software and not an actual driver, because when I plug my receiver in, it lights up but comes up as "Installing device driver software..." then it says "Installation failed..." and registers the device as an unknown device.

I still press the button to sync it, and then I press the sync button on my controller, my controller recognizes the receiver and connects to it (both devices stop trying to sync) but as the receiver is not recognized by my computer, it is not communicating that a controller is connected.

This is frustrating because there is no documentation for honest support. Going to the support page it lists several things "Windows, Hardware, Audio" etc, but under NONE of these categories is this product, leading me to believe Microsoft simply doesn't give a ____ about me or my problem. Then when I go to support and try and type in my PID (product identification number) it says there is a problem with the number.
