Error: (8920,1234) "Norton LiveUpdate was unable to install an update" appears when I run LiveUpdate in my Norton product

To check if the issue you are experiencing is related to a known system problem or outage, visit Norton Services Status.

STEP 1

Run LiveUpdate after 24 hours

  • An intermittent problem with the LiveUpdate servers can cause this error. You can be assured that this problem is fixed quickly. Wait for 24 hours and then run LiveUpdate again.

    You may notice this error when you run LiveUpdate manually. LiveUpdate downloads these updates automatically, and often by the time you manually run LiveUpdate again, the updates will be installed successfully.

    If the virus definitions of your Norton product are out of date, you can use Intelligent Updater to update it.

STEP 2

Check your Virus Definitions date

  1. Start your Norton product.

  2. In the main window, Under You Are Protected, check for the date next to Protection Updates.

  3. Depending on your situation, do one of the following:

    • If the time is less than one day, then wait for 24 hours and then run LiveUpdate again.

    • If the time is more than one day, go to Step 3 to update your virus definitions using Intelligent Updater.

STEP 3

Update your virus definitions using Intelligent Updater

  1. Go to the Intelligent Updater downloads page.

  2. To choose the correct definition set, you need to know the name and version of your Norton product and the version of Windows.

  3. Depending on your version of Windows and Norton product, download the appropriate definition set.

    Norton product version

    Windows 32-bit platform

    e.g. 20170126-020-v5i32.exe

    e.g. 20170126-020-v5i64.exe

  4. Save the file to the Windows desktop.

  5. On the desktop, double-click the file that you downloaded.
