How To: Update your existing license file using the Update License tool


The Update License tool is installed during the License Manager installation. Use this tool to add and update license keycodes on the license server.


  1. Save the license file as a .txt file in a safe location before opening it.
    Do NOT save this file in C:\Program Files\ESRI\License.
  2. Verify that the hardware key number in the file matches the number printed on the hardware key plugged into the license manager server.
  3. Open the Update License Utility located at Start > Programs > ArcGIS > 'License Manager' > 'Update License Utility' and follow the instructions on the Update License Utility dialogs.
  4. After Updating the license file the license manager service will need to be restarted from Windows Services.
