title: How to suppress unneeded InstallShield InstallScript MSI dialogs?
body: <p>I have an InstallShield 2009 'InstallScript MSI' project which shows 2 dialogs which are not necessary in my installation:</p>
  
  <pre><code>Customer Information
    Setup Type
  </code></pre>
  
  <p>How can I disable those 2 dialogs?   Under 'User Interface', the 'All Dialogs' tree lists those dialogs, but they are all grayed out, and cannot be disabled or changed.</p>
