title: PostBuildEvent in WindowsInstaller project returns error code '1'
body: <p>I have a Windows Installer (VS 2008) project and I want to create a very simple post build event, which just opens the target folder, with the installer selected. </p>
  
  <p>So I've typed the following in the PostBuildEvent field:</p>
  
  <blockquote>
    <p>explorer.exe /select, $(BuiltOuputPath)</p>
  </blockquote>
  
  <p>The problem is I get the following error:</p>
  
  <blockquote>
    <p>ERROR: Error de 'PostBuildEvent' con el código de error '1' 'Error no
    especificado'</p>
  </blockquote>
  
  <p>Which translates as something like:</p>
  
  <blockquote>
    <p>ERROR: 'PostBuildEvent' error with error code '1' 'Unspecified error'</p>
  </blockquote>
  
  <p>The thing is, the folder opens, with the installer selected and all, but it keeps giving me error. </p>
  
  <p>So, am I doing something wrong?</p>
