I doubt you will find this type of information on a site officially hosted by Corel Corporation. As pointed out by others, CorelDRAW Graphics Suite X5 is a commercial product that you have to purchase if you want to use. Many people at Corel work very hard to develop CorelDRAW, and paying for the software not only pays the salaries for those who work on it, but also enable the company to continue the development of future versions.
