Error: (8920,1234) "Norton LiveUpdate was unable to install an update"

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.

1. Open your Norton device security product.

   If you see the My Norton window, next to Device Security, click Open.

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:
