If you follow the links from the download page there is the list of fixures available in the student version.

The Demo (which is the same installer as the full version) uses the full library, so you can just download that and see the full library. There isn't an online list for the full library.

You could also use the avolites personalities website (personalities.avolites.com) to check specific fixtures, as they show if a fixture exists in the Capture library, as they have native capture integration in their consoles.
