Network licensing errors during software startup in AutoCAD Civil 3D 2011

If these solutions do not resolve the installation error, the additional tests listed below will help determine the cause of the problem.
  • Network licensing errors often indicate a problem with the license manager. See the following solution for details on configuring and troubleshooting the Autodesk Network License Manager: Problems configuring the Autodesk Network License Manager (FlexLM).
  • Many times errors occur when license servers are changed, added or removed. Make sure that your product is looking to the correct license manager. Change how your AutoCAD-based software locates the license manager by setting an environment variable on the client workstations. For more information, refer to the following solution: Specifying license servers using the ADSKFLEX_LICENSE_FILE environment variable.
  • Make sure that client machines can ping the license manager and the license manager can ping the clients by hostname. If this does not work, it indicates a networking problem that will need to be addressed before network licensing will work. Contact your network administrator or IT professional for additional assistance.
  • If the Autodesk product does not display an error code, or you want a more descriptive response, follow the instructions in the following solution to increase the amount of information returned when a network licensing error occurs: Increasing verbosity of FLEXlm® errors. This information is particularly useful when troubleshooting Revit licensing issues.
  • For a complete description of all error codes, refer to the Macrovision FLEXlm® documentation (in HTML format), which is included with the installation of the Autodesk Network License Manager. By default, the FLEXlm documentation is located in the C:\Program Files\Autodesk Network License Manager\Docs\FlexUser directory.
If you have worked through the standard troubleshooting steps and were not able to resolve the issue, follow this link for additional technical assistance.
