--- Comment #4 from RevenantX doomrevx@gmail.com 2013-09-26 09:43:00 CDT --- You can create empty folder and open unity in that folder. It is not necessarily create project from unity. But you can click "Create Project" and unity create empty folder, then choose "Open Project" and choose new created folder (that created by unity)
