Hello Li,this is not quite correct. If you have a student email address, containing e.g. ".edu" or "university", you can request a free academic license.
Use the menu item of Elbe, see attachment, which leads you to the licensing web page.
Are you willing to help me? Jens Am .01.2014, 10:59 Uhr, schrieb li yongjian <lyj238 at gmail.com>:
I have downloaded Elbe, but it seems that this is not a free software? I cannot use it.
