v25 midi controller doesn't make sound when plugged into computer and Xpand!2 won't run

I recently received a v25 midi controller and when I attempted to download the Xpan!2 software to my HP ProBook computer the software would not run. Also when I tried to use the controller with the abelton software I could not get any sound to be made. How should I get the controller to make sound?
