Issue: You need to activate and register your stand-alone Autodesk product.
During product activation, your serial number and product key are verified and licensed to run on your computer. Activation is only required for Stand Alone Autodesk licenses. If you have a serial number and product key when you install your software, activation will be part of the installation process.
For a video walkthrough of the process, see: Activation and Post-Installation Tasks for Autodesk products and suites.
