title: execute code just when install the application using installshield
body: <p>I am just wondering if it is possible to run a small code just once when the application is installing.</p>
  
  <p>I would like to create a registry with the installation path. The reason why I need that because I have a windows service in my application as well, which install path always changes to system32.</p>
  
  <p>I have an ini file which is created in the installation folder at installation. I need to reach that file with my service and windows form as well.</p>
