Entering an incorrect product key will result in activation errors. Autodesk® AutoCAD® 2019 Internet Security Hotfix Products and versions covered Oct 30 2018Download Add to Collection As part of Autodesk’s ongoing efforts to provide the best security possible to our customers, we are proactively applying security updates to our products that will be required by October 17th. Note: Make sure you use 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 2020 as a single product requires product key 001L1, but installing AutoCAD 2020 from the AutoCAD Design Suite Premium 2020 requires product key 768L1.

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.
