Solution or Workaround
First, verify that the License Path indicated in the error message is the correct host name or IP address of the license manager system. If the License Path is 'Not_Set', then Desktop Administrator has not been configured with the location of the License Manager. <a href='https://support.esri.com/en/knowledgebase/techarticles/detail/26572' target='_blank'>FAQ: Why is 'Not_Set' listed in the Desktop Administrator License Manager folder?</a>
If the 'License Path' is correct, then the license manager may not be running. If the license manager system cannot be accessed, contact a license administrator for assistance. Otherwise, perform the following troubleshooting steps on the license manager system.
Check the Configuration using Services radio button.
Select the Start/Stop/Reread tab.
Click Stop Server.
Click Start Server.
Perform a Status Enquiry to confirm that the licenses are available:
Click the Server Status tab and click the 'Perform status enquiry' button. 'Display Everything' should be selected.
Verify that there are no errors in the status enquiry. <a href='https://support.esri.com/en/knowledgebase/techarticles/detail/37583' target='_blank'>[O] LMStatus</a>
Check the license manager log file for any errors.
On the Config Services tab, click View Log. <a href='https://support.esri.com/en/knowledgebase/techarticles/detail/21944' target='_blank'>Problem: Messages in the license manager log file</a>
If the status enquiry and log files do not indicate any errors, there may be a firewall running on the license manager system. <a href='https://support.esri.com/en/knowledgebase/techarticles/detail/26134' target='_blank'>How To: Configure Windows XP's Internet Connection Firewall to work with the License Manager</a>
