Request for the serial number and product key mistake.
I'm a student of the design program. My class need 3ds max and autocad version 2015
I got 2 serial number and product key for the both programs which are .... and .... .
But I was confuse during downloaded the programs. I downloaded 3ds max 2017 then I download 3ds max 2015. The result is I lost all my keys which one is need for autocad 2015. Would you be able to help me to receive my key back for autocad 2015, and delete the one that I made my mistake (3ds max 2017). If I misunderstand anythings, your suggestions will be kind. Thanks you in advance.
