title: GlassFish server installation executable does not open
body: <p>I am trying to install GLassfish server using execuatable <strong>glassfish-3.1.2.2-windows.exe</strong>
  When i try to open the executable,  after the message <strong>Launching Java 2(TM) Runtime Environment</strong> nothing happens.</p>
  
  <p>I already have Java installed.. if i am correct i tried getting the version from cmd prompt.. it has given me the version </p>
  
  <p>java version "1.7.0_51"
  Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
  Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)</p>
  
  <p>Now m not sure if the problem lies with environment variable.. but i have tried setting up that too.. but still the same issue.
  Seems like m missing something..
  Please help...</p>
