It actualy doesn't finish there. The installer is taking a fingerprint of the current system hardware and generating an installation key which must be accompanied with a unlock / activation key provided by the support people. This key works for this hardware / installation id only. The key is stored inside the encrypted source code - which is done by the same encrypted source code... It's working 100% without problem. I've done some tests... it is practicaly very difficult for someone to copy the code - "just like that". Glad that I heard your reply makes me feel good.
