title: Not able to use NativeProcessInfo and other related classes
body: <p>I have an AIR application in which I have to start some native applications in a windows machine.But the problem I am facing is that whenever I try to create a <code>NativeProcess</code> instance,I am getting a compiler error because <code>NativeProcess</code> is not getting imported into the project.I tried <code>import flash.desktop.*;</code> Even then no use.I have also added <code>&lt;supportedProfiles&gt;extendedDesktop&lt;/supportedProfiles&gt;</code>
  in the application descriptor file.I am using FlashBuilder 4 with Flex 4 SDK</p>
  
  <p>Anything else I need to do to make it work?</p>
