The InstallComplete dialog shows "Back" or "Cancel" buttons, but they are disabled. The should be completely removed.
There are a bunch of other dialogs that have buttons that are always disabled, so therefore should just be removed. All controls from the SetupInterrupted Dialog should removed, because this dialog is never shown anymore.
