That doesnt necessarily make it legal. Software that schools use are licenced to the school for its uses only. Who uses the software and how it is used is determined by the licence. Typicaly any staff, faculty or student can use the software inside of the instatution. Non students, like Aladin, would not be legaly allowed to use the software.
Looking at the site
http://www.crocodile-clips.com/Videos_and_Downloads/Downloads/, it appears that you cannot use the software directly without out registering for the demo or buying a licence
I don't see why that would matter. licences/copy rights applies to any form of software
