Entering an incorrect product key will result in activation errors for that product. Upgrading a Revit installation involves moving from a previous release of the software to the newest release. Note: Please ensure you are using the correct product key for the Autodesk product and version you are installing. Autodesk® AutoCADreg Revit LT Suite can help smaller architecture firms transition to Building Information Modeling (BIM), with both Autodeskreg Revit LT software and the familiar drafting tools of AutoCAD LTreg available together in one suite. The same version of AutoCAD is in both software packages but the product key differentiates one package from the other. Currently available Revit LT versions for free downloading and install is 20. For example, installing AutoCAD 2019 as a point product requires product key 001K1, but installing AutoCAD 2019 from the AutoCAD Design Suite Premium 2019 requires product key 768K1. The Revit LT 2021 updates are cumulative and include all changes from previously released Revit LT 2021 updates.

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.
