Leonardo Drivers not Installing on Windows 7

Today, I got a new Arduino Leonardo. When I plug it in, it cant find the drivers for "Arduino Leonardo." I tried going into "devices" and updating the drivers, but it says "Windows has determined that the best drivers are already installed." I am greatly confused because it says there are no drivers installed yet. How can I fix this?

If the arduino is not broken, try http://arduino.cc/forum/index.php/topic,118440.0.html it forces the right drivers
