The problem with this is that the person installing it has to have an internet connection. If someone tries to run the setup again off the same CD it will once again contact the server with the identifier and receive a response that it is flagged and no longer usable. The server then returns a cryptographic key along with binary data that is necessary to run the setup. It sends the unique identifier and the server flags it as used. When the setup program is ran, it communicates with a server somewhere. The only way I can see this being possible is burning a specific identifier into each disc. What stops an user from creating an ISO of the CD and making tons of copies before running anything even if somehow the setup program destroyed the CD?
