I'm trying to activate Inventor Professional 2013 and AutoCad 2013 and, in both cases, I get the same message: error 400 during activation. I don't know what can I do, could you please help me?
I have a student account, and I'm trying to install both programs in two different computers for my personal use (one is in my house and one is my laptop, to use it in the University too). Could it be any problem with this?
Thank you very much for your help.
My understanding is that with the Student version, you can only install and use on one machine. That might be your issue.
