comment Authentication of machine before installation (to stop piracy)
@supra , its difficult to see the connection , but let me explain , the moment you copy the software its beyond your hands you cant prevent from any one doing anything withit especially if its running it . the prevention might come from preventing copying the file itself which is impossible. Most of the licensing software fail here even if you tie the installation with MAC address too, there is nothing one could do it can be spoofed easily
