Got it, no cross posting. sorry about that.
Yup the content of the CD is copyrighted by our company. We wanted to produce one CD of our program for every user. Multiple users can use a single computer so we have to detect if the current user’s CD is already activated/licensed by reading it’s Serial Key. Since we produce copies in duplicator with identical serial keys. Multiple users in a single unit would be a problem. I need help please. Thank you very much
