Ohhh, thanks, I downloaded, but how can I use it?, because I try make new installer but I don't know how set the serial number...thanks again...
There is an example script in there. Setting up a serial number is another matter that you will have to solve yourself.
One possibility is to have an online script to validate a serial and output a value depending on its validity.
Another option is to hard code your serial but of course this isn't a good idea.
