title: installshield launch exe from source media
body: <p>I have an installshield msi project that produces CD-ROM files.</p>
  
  <p>I know how to set a custom action in order to launch an exe file stored in binary table.</p>
  
  <p>What i want to do is to launch an exe file that is at the source media root directory and it is not copied at the installation directory.</p>
  
  <p>I do not want to add it at the binary table because i want to be able to change the file without building again the installer.</p>
  
  <p>any ideas?</p>
  
  <p>Thanks </p>
