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.

  • 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.
  • Restart the License Manager:

    Click Start > Programs > ArcInfo > License Manager > License Manager Tools.

    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.
