title: eclipse cannot start without any error message
body: <p>windows 7, 32 bit, two jdk, one is 1.5, another is 1.7</p>
  
  <p>I got two eclipse from my colleague, kelper and luna, they works fine.</p>
  
  <p>I downloaded one from official site today, luna too, unzipped it, then double clicked eclipse.exe to open it. However, eclipse didn't run, there was no loading page as well as any error message.</p>
  
  <p>I tried to add :</p>
  
  <pre><code>-vm
  C:\Program Files\jdk1.7\jre\bin\javaw.exe
  </code></pre>
  
  <p>to eclipse.ini, it still didn't work.</p>
