Product keys are required for installation of Autodesk products and are used to differentiate products that are both sold independently and as part of a product suite. For example, installing AutoCAD 2016 as a point product requires product key 001H1, but installing AutoCAD 2016 from the Autodesk Product Design Suite Ultimate 2016 requires product key 781H1. The same version of AutoCAD is in both software packages but the product key differentiates one package from the other. Note:Please ensure you are using the correct product key for the Autodesk product and version you are installing. Entering an incorrect product key will result in activation errors for that product.
The product keys for Autodesk 2016 products are as follows: Product Name Product Key Autodesk 3ds Max 2016 128H1 Autodesk 3ds Max Entertainment Creation Suite Standard 2016 661H1 Autodesk 3ds Max with Softimage 2016 978H1 Autodesk Advance Concrete 2016 960H1 Autodesk Advance Steel 2016 959H1 Autodesk Alias AutoStudio 2016 966H1 Autodesk Alias.
