Question

When attempting to launch Structural Designer, the License Manager is launched instead, displaying "Error 18" within the Status page.

Answer

  • Check whether a license has been issued for the version of Structural Designer that you have installed - if not, you can request this from your local Trimble office
  • If you have been issued a license for the version you have installed, ensure that this has been activated on your server
  • If your license has been activated on your server, ensure that you have configured your licensing settings to use the correct server as shown below
    1. Go to Start > All Apps > Tekla > System and User settings - this will launch the Software Licensing Configuration
    2. Under the System group, select Products on the left, then on the right select Tekla Structural Designer
    3. Ensure that the License Method is set to Server and the server name is set to (Default) 
    4.  Select the License Server page on the left, then on the right click Find - this should find your license server. Alternatively you can manually type the IP address of the server
    5. Close the Licensing Configuration and Launch Structural Designer
