It looks like the drivers may need to be installed correctly. Try walking through the steps on our 'Installing Arduino Drivers' wiki page and see if that solves the issue for you. If it doesn't, there may be something on the computer that is preventing the driver from installing properly (such as a group policy or security program) that will need to be addressed.
