Reinstalling OrangeCD as default

I understand the default cd player is reset when uninstalling the suite but it seems I have to mark the "Check if default on startup" with the preferences each time after the latest installation to allow me to confirm the OrangeCD is the default . The "Make default player" is already marked but has no effect on stopping the Microsoft player starting up. Any help appreciated
