If I protect a program with a registration code and sell the first copy, when I sell the next copy, if I put the previous registration in the banned codes section, will that keep the first copy's registration code from working for anyone else if the first person would try to hand out free versions of my program along with their registration code?
thanks...Bud
That will lock the registration code only in new installers you make. The first person can distribute their installer with their registration code.
Is there a way to make the registration for 1 use only?
Bud
No, to do that your installer would have to connect to a server, check if the registration code has been used on another machine, if not, register it, etc. That's a whole different system.
What about embedding the Mac Address of the host in the license file, writing the license file to the registry on install and then checking the Mac Address of the current host with the Mac Address stored in the registry i if they match run your application if they dont then abort - would this approach solve Budd's problem and is it doable ?
What if they get a new network card?
OK then - the CPU ID, Windows Serial Number - whatever .....
