Dear all
many thanks for your contribution and I am sorry that I can not write in arabic right now.
My concern is that, I did install this program three times followng the step -by-step as described in the first post. My first installation completed and asked to give a true e-mail. I did it and validate as requested. At the end I did launch the program and get the bad result, License required.
So I read all the posts here and uninstalled every thing after making a Root research. Now I re-install but it goes straite to the downloadas soon as the installation completed without asking me the e-mail any more . It is amazing to see how it did work for certain and other not.
Many thanks anyway.
