GeneralActivation Codes Pin

Activation codes used to stop unauthorized software copy. One way to generate activation codes, gather some unique information (like CPU id, hard disk id, network card id etc.) from the system and write somewhere in the disk or use ImageAddCertificate() API on Windows to put this information in your executable itself.

Read your activation code by reading activation data through ImageGetCertificateData() and validate it. But what to do if due to some reason user change his network card or CPU etc.

If we need to install the software again ? No, generally all professional software take care of this situation.

I think, one idea could be gather such 4 - 5 unique IDs and make a rule that if any of 2 ids are same, continue execution otherwise show error unauthorized copy Cool | :cool: .

There could some more better ways to deal this. Starting this thread to discuss more about activation codes generation.
