So, after paying i am at the at "My Downloads" Area.
1. There i didn't see the "No 'www' or 'http://'" and i put all the domains with www. is there a problem?
2. First i will build the site locally and then i will upload it. What must i do to take licence number for local host?
on Localhost you need to manually enter the license number form the my downloads page. into the ijoomla product manager. you can then use the ijoomla installer as normal
Please not that we don't offer support for localhost installations your site must be available to connect from a live server
