The license of the program can be ordered online through specialized e-commerce reseller companies or PayPal through secure forms.
Please see http://www.photochances.com/order to access the ordering forms and options.
Once your order is processed you will receive by email your activation code. It's somewhat like a personal password with a unique key that you enter easily into the program. Once the program recognizes your code it will remove the limitations of the Demo mode. Also it will allow to remove the watermarks on images you saved previously with the program in evaluation mode.
Please consider purchasing the license of the program if you will use it. The low price, compared to the effort put on its development and fine tuning, is small but it contributes and compensates the effort put on its development (many many many hours of programming) . Your contribution will give a meaning to that effort and feed the evolution of the program. (Of course if you like it! :-)
