Entering an incorrect product key will result in activation errors for that product. Note: Please ensure you are using the correct product key for the Autodesk product and version you are installing.

The same version of AutoCAD is in both software packages but the product key differentiates one package from the other. For example, installing AutoCAD 2018 as a point product requires product key 001J1, but installing AutoCAD 2018 from the AutoCAD Design Suite Premium 2018 requires product key 768J1.

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.
