title: InstallShield execute uninstall custom action
body: <p>How do I execute a Custom Action when performing an uninstall?
  The Custom Action is within a Basic MSI project and I am using InstallShield 2010 Premier.
  I have tried setting the Install UI Sequence to After SetupProgress and Install UI Condition to REMOVE=”ALL”, but the action is not getting called during the uninstall process.</p>
  
  <p>Any help would be greatly appreciated.</p>
