So I installed AutoCad 2013, however just recently my computer crashed and had to reboot itself. Because of this I no longer have autocad installed on my computer and it wont allow me to re-instal it! What can I do? Or is there a possibility that I could get another key??
You mentioned, "wont allow me to re-install it", can you provide more details or a specific error message?
Indeed if a computer crashes, what needs to be done is to re-install the Product and then re-activate it. Do you have a Student License or a Commercial License?
