   {
      if ( mySavedState == nullptr )
      {
         Console::WriteLine( "Uninstallation Error !" );
      }
      else
      {
         Installer::Uninstall( mySavedState );
         Console::WriteLine( "The Uninstall method of 'MyInstallerSample' has been called" );
      }
   }
// Override 'Uninstall' method of Installer class.
public override void Uninstall( IDictionary mySavedState )
{  
   if (mySavedState == null)
   {
      Console.WriteLine("Uninstallation Error !");
   }
   else
   {
      base.Uninstall( mySavedState );
      Console.WriteLine( "The Uninstall method of 'MyInstallerSample' has been called" );
   }
