Your specific issue, as shown in your thread that you linked, is that you are also on an older version of Windows 10, but not on LTSB as the OP of the thread is having issues with. 1607 is not supported by Microsoft any longer which I am sure you are aware of, making it extremely vulnerable. Conversely, There have been a few Norton product releases after version 22.22.6.10, did you attempt to update in the past and had issues or just updating now? TIA.
