body: <ul>
  <li>Using advanced user interface project for packing my wix msi with
            installer.I hope this project type is suitable for me . Now want to validate key via registration page (Customized dialog),so how can we do this action in install shield ?
  I found one option in button
            control Events and its has option browse for dll action but its not
            working for me.I have a C# windows installer CA library for key
            validation but its not working in this action.</li>
