Zune software can't be installed.

Question

Zune software can't be installed onto BUILD tablet. It requireds .NET Framework Runtime 2.0.

Answer 1

Have you tried installing the required .net framework? LOL

Answer 2

As calingasan correctly deduced, you need to enable the .NET framework runtime. You can do this from "turn windows features on or off" or I think it should automatically prompt you to enable that feature when you attempt to install Zune.
