title: How do I pass a default 'install location' to the RtfLicense bootstrapper?
body: <p>I'm using an rtflicence standard bootstrapper to install dotnet before my poject msi in a chain. </p>
  
  <p>I noticed that there's an 'options' button which displays an install location dialog and allows the user to change the default installation directory. </p>
  
  <p>I need to either:</p>
  
  <ol>
  <li>Prevent this options button from being displayed, or</li>
  <li>Populate the install location with a default path, and pass this back to the installer should the user change it. </li>
  </ol>
  
  <p>I read that it's possible to pass Burn variables to msipackages from bootstrapper but I haven't found any further details and would appreciate being pointed in the right direction. </p>
  
  <p>Thanks</p>
