Error: (8921,240) "Norton LiveUpdate has completed with an unknown error" when I run LiveUpdate in my Norton product

These steps are for the current version of the Norton products. If you have an older version or if you do not know your product version, go to Norton Update Center.

STEP 1

Run LiveUpdate

  1. Start your Norton product.

  2. In the main window, click Security, and then click LiveUpdate.

  3. When Norton LiveUpdate is finished, click OK.

  4. Run LiveUpdate until you see the message, "Your Norton product has the latest protection updates."

  5. Exit all the programs, and restart the computer.

STEP 2

Download and run the Norton Remove and Reinstall tool

    If you have received your Norton product from your service provider, skip this step, and run the Norton Removal Tool.

  1. Download the Norton Remove and Reinstall tool.

    Save the file to the Windows desktop.

  2. On the Windows desktop, double-click the NRnR icon.

  3. Follow the on-screen instructions.

  4. Restart the computer.

    Your computer may be restarted more than once, and you may be asked to repeat some steps after the computer restarts.

Thank you!
