I also had similar problems with Vista and StarryNight. The update which was supposed to solve the Vista problems required installation of an earlier version first. How do you update to a Vista compatible version when the non-Vista compatible version will not install?
I eventually gave up (much to Rob's disappointment - CoombellKid). Rob made a number of suggestions which may solve your problems:

They did not solve mine.
I am now using Voyager instead which installs fine under Vista.
