Installation & Licensing

[#1]

i have autocad 2011 install but its the 'unregistered version.' how do i get a license? (or better yet, how do i get the free 3 yr student trial?)

[#2]

A. buy it from a dealer?

B. if a student, with you can get the educational version, just be aware that it is deliberately non-usable for commercial work, plotting banner, etc. 

C. probably not possible to get the 2011 version anymore -- 2012 is what Adesk has on offer
