title: flash builder - export build is generating airi file instead of air
body: <p>This is my first time I ever created an air installer. When I clicked on "Export release build..." and clicked on finish, it is creating "projectname.AIRI" file instead of "projectname.air" file.</p>
  
  <p>I confirm below check</p>
  
  <p>I did not change the default name
  Tried to find using what an airi can open with, but there is nothing as such
  Renamed airi to air and tried to open the file (icon has changed to air installer) but it gave me error "corrupted installer"</p>
  
  <p>Can some one help me what to do? Is it that complicated?</p>
