solidworks 2012 model open issue

If you have solidworks???
Why don't you make the square box yourselve.....
This is a community for engineers and designers who know how to work with 3d software.....if you do not know how to make a square box (so very basic) why are you "here"????
Give it a try...and only than if you get stuck ask a question.....but what you are doing.....very weird!!!!!

Does it have to be a box? otherwise i believe there are several .sldprt 2012 in the library.

How it locate ? I want exact part that should be made in 2012 version
