Issue Details

 

Solution

• • Increase the Activation Timeout in the User Preferences File:

    1. Close NILM and the NILM Activation Wizard if they are open.

    2. Open the following file in a Notepad or other text editor:
       C:\ProgramData\National Instruments\License Manager\Data\UserPreferences.pref

    3. Add the following line under the <UserPreferences> element to configure the HTTP client timeout in seconds. The example shows 300 seconds which is the maximum supported, but you can configure any value between 101 and 300 seconds, inclusive:
       <HttpClientTimeout>300</HttpClientTimeout>

    4. Save and close the user preferences file.

  • Activate the Licenses
    • Activating All Licenses at Once

      1. Launch the NILM Utility and attempt to re-activate all licenses by clicking the "Activate Software" button at the top. 

      2. If the activation still times out, follow the steps below to activate the licenses in batches.

    • Activating in Batches

      1. Back up the C:\ProgramData\National Instruments\License Manager\Licenses folder. Name the backup folder UnactivatedLicensesBackup. This is crucial to restore the original license files if needed.

      2. Delete all the licenses in the Licenses folder.

      3. Copy the first 20 licenses from UnactivatedLicensesBackup to the Licenses folder.

      4. Launch the NILM Utility and attempt to re-activate all licenses by clicking the "Activate Software" button at the top.

      5. All licenses should be activated. If not, retry with a smaller set of licenses.

      6. Once the 20 licenses are activated, move them to another backup folder named ActivatedLicensesBackup.

      7. Close the NILM Activation Wizard and the NILM Utility.

      8. Repeat the above steps until all the required licenses are activated in batches.

      9. After all licenses are activated, copy all activated licenses from the ActivatedLicensesBackup folder back to the Licenses folder.
