  # - NO: Deactivate any previous version of Mouse Locator
  # - YES: Close the System Preferences, if open
  # - NO: Remove any previously installed Mouse Locator
  # - YES: Install a new version of Mouse Locator into:
  #     {HomeFolder}/Library/PreferencePanes/
  # - YES: Activate Mouse Locator, if previously active
  # - NO: Open the System Preferences, and display the Mouse Locator
  #   Preferences Pane
