Hi Wayne,
I can't quite tell from your post if you are a Mac or Windows or Linux user so I'm not sure which Updater you are looking for, however, I DID find a live link to 2 updaters for a very old version of RayDream 3D - version 1: -> for both Mac and Windows! Note: free membership to that site's forum allows a download
Found link here:
Downloads | RayDream :: Keep it alive
I like the challenge of data-mining for old applications, and I like helping folks where I can - but I really have nothing to do with whomever owns or writes the apps so... its 'user beware' regarding whether it is the correct version or even works or not.
All the best ^5
