"Short of memory on program drive I chose the Rewire 'driver' on the checkbox."
Could you elaborate on this? I don't understand how this would be a workaround for lack of disk space. It should not be a massive install and if you are THAT low on space... well time to clean up the drive or buy a new one. Rewiring it seems like it would totally defeat a lot of the benefits of ARA integration.
Anyway... if you installed it normally it should show up under Region FX but you may just need to do a VST scan (making sure the Celemony/Melodyne folder is included) to make it show up.
