says
HTML5 Builder is Embarcadero's new web and mobile app development solution. With HTML5 Builder, you also get access to licenses of Embarcadero's previous web and mobile app development tool, RadPHP. HTML5 Builder provides access to RadPHP XE2 and RadPHP XE.
If you purchase individual named user licenses, just go to http://www.embarcadero.com/xe3-earlier-versions after you register your HTML5 Builder product serial number. You can enter your registered HTML5 Builder serial number and get a serial number and download for RadPHP XE2 and XE. That license will be tied to your user account and cannot be given away or sold.
You must request RadPHP licenses within 180 days of your purchase of HTML5 Builder.
