title: Not able to run Eclipse Application. Can't even start Eclipse IDE
body: <p>I have an RCP product which doesn't run. Then I installed Eclipse freshly, and when I open Eclipse.exe it doesn't open Eclipse IDE. I get the error: NoClassDefFoundError: com/mercury/javashared/agentloader/AgentBootstrap  (Please see complete trace below).</p>
  
  <p>System has latest jdk,jre installed. What could be the reason for that error? 
  (PS: The same eclipse archieve when unzipped on a different machine works fine). I am able to run eclipse and my eclipse rcp product there)</p>

  <p><strong>UPDATE:</strong>
  I had QTP (Quick Test Pro) installed on the machine. When I uninstalled QTP now I am able to both RCP product and Eclipse.exe.</p>
  
  <p>Now, whats the relation between QTP and Eclipse? I want both to coexist.</p>
