A client just received a new T520. We ordered the Lenovo Mini Wireless mouse and keyboard. We attempted to install the device via the CD and also from the product page on Lenovo. The issue is that when we plug the dongle in it attempts to install four drivers but only three out of the four install. The problem driver is the USB Human Interface Driver. It has the yellow triangle in device manager. When told to update manually it states the file cannot be found. When trying to manually update it states "access is denied." The problem looks to be that the driver is not signed. If I restart and press F8 and select "disable driver signature enforcement" then the computer starts up with the keyboard and mouse working normally.
Since this is a Lenovo laptop and Lenovo accessory I don't see why there is this issue with getting the driver installed / signed. Any advice on the matter will be helpful.

I tried the scan as was suggested but it stated there were no integrity issues. Restarted and tried to install the hardware but the same results. Any other suggestions are much appriciated.
