Issue:When you launch AutoCAD or AutoCAD LT 2018 or any vertical product (AutoCAD MEP, AutoCAD Civil 3D etc.), the application opens and the following “License Error” message is displayed:
The License manager is not functioning or is improperly installed. AutoCAD will shut down now.
Solution:Perform a Clean Uninstall and then reinstall the software.
- Note: The uninstall process will affect other Autodesk products already installed on your computer. Make backups and get installation files (from Autodesk Account or Virtual Agent) before uninstalling.
The software DMX workshop (v7.8) have been reported to cause also this issue when AutoCAD 2018 is installed from the Autodesk Desktop App. In this case, AutoCAD 2018 will install but the license service will fail producing the License Error shown above.
To solve this, uninstall DMX workshop 7.8 from the system, then run the AutoCAD 2018 installation again.
