When you re-start AutoCAD, you will again be prompted to select your license type. If you happen to have a drawing open when you change license type, or your network license manager is offline or inaccessible, you will be prompted to save your work, if you need to. When you are ready to switch to network or standalone (desktop) license, the About command then Manage License shows the option to Change License Type. If your license manager isn't updated yet, you can start using AutoCAD in trial mode that lasts a maximum of 30 days. Once you select a license type, you will be prompted for the serial number and product key. When you install AutoCAD 2017 for the first time you are not prompted for the serial number, product key or license type until you run it for the first time. Starting with AutoCAD 2017 it's now much easier to change the license type from Trial to Stand Alone or to Network in the program.
