title: Install directory from deployment projects
body: <p>I'm developing an application and I'm going to deploy it with the help of a deployment project (which is gonna create an installer).</p>
  
  <p>At one step in the installer, it will allow the user to change the installation folder for the application.</p>
  
  <p>I need to know what this folder is because there will be some files saved there that I need to use from another DLL file. How can I programmatically get this installation folder?</p>
  
  <p>Thank you!</p>
