When creating the CD/DVD, create a digest (checksum) from the identifiers of all major hardware components of the system and encrypt the contents of all data with this digest. Then, when the software is being run, that should create the digest, too, and decrypt data with it. If the digest is obviously wrong, display an error message ("wrong system") and abort execution.
Doesn't that SOUND simple?
