I just got my new Latitude E6540 and noticed that there isn't any kind of onscreen display for volume control etc. Found on the forums that Dell QuickSet software is providing those. I downloaded the software and tried to install it, but got only message that my operating system (Windows 7, 64 bit) is not supported. And yes, I downloaded version that should support W7, 64 bit.

How am I able to install QuickSet to my laptop or get the onscreen display somehow?
