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. The same version of AutoCAD is in both software packages but the product key differentiates one package from the other. Please ensure you are using the correct product key for the Autodesk product and version you are installing.
