title: Setup project for a windows service and the event log
body: <p>I got a setup project that installs a windows service.</p>
  
  <p>We are registering a event log source in a custom log which should be used by the winservice project (how and why is not important).</p>
  
  <p>My problem is that the setup project tries to create an event log source per default. By doing so it get's an error message (<code>"Error 1001" source XXX already exists on local computer</code>) and rolls back.</p>
  
  <p>I have looked everywhere and I cannot find where the registration is done or how I can turn it off. </p>
  
  <p>How can I force the windows service or setup project to NOT create an event log source?</p>
