Site 1: They seem to be Media Kits (whatever they are...), see below for their statement.
Please Note: Media Kits are disks containing software that can only be used if your organisation has an existing Licence Agreement. As part of such agreements, users will be provided with a licence key that will enable the software. Without the required licence key, the software will not install.
