Thank you all. I explain what I did to do it. Very simple but what I want: I find the host id of system (using ipconfig) and create a hash code based on it.(some math, md5 and functions). the code for licensing is about 15 lines and is very fast. I needed 20 licenses and I wrote a keygen for myself.
