I have recently downloaded autocad 2012 and autocad lt 2012 essentials for my laptop.
I was issued a product key and serial number they given for me after i registered. The serial number was accepted when i typed it in but the product key refuses to be accepted. I really dont know what to do, I need to start working and my auto cad is not activated.
Please follow this link for a list of product keys for the past four versions of our products.
Let me know if this helps or if you still get an error.
