Yes, the instructions/info in the box is seriously lacking. I had the same problem. Although they don't tell you, you need to go to the web site listed in the box to install software. If you just activate batteries and plug in the receiver, the basic functions will work. If you want the other buttons, like I do, you have to install their software. Don't use the SmartInstaller, but scroll down and select the 64- or 32-bit version, as appropriate. The SmartInstaller wasn't smart enough to figure out what my Dell machine was.
