I recently downloaded AutoCAD 2012 as a student to use for schoolwork on my laptop.However, when I tried to download AutoCAD Architecture 2010 on my laptop for the same purpose, it said that I did not have the right operating system, so I instead installed it on another computer. The download was successful this time, but when I tried to use the program, it told me that it could not work because a) it did not install correctly or b) I do not have permission to use it. How would I install it correctly or get permission to use it? Thank you to anyone who helps me with this.
