IANAL and I have no idea where in the world you are, but downloading (as in with an http client) an ISO[1] is often treated rather dramatically very differently than distributing an ISO (as in a p2p torrent).

Alternatively: eBay. Encarta 96 CD-ROMs are available for about $20 in the US, delivered.
