Why LiveUpdate service is missing from Services?

it should be present, when you launch the Liveupdate from SEPM , do you see "LUCOMS~1.EXE" in the task manager process?

if not, then you need to reinstall LU.

Before uninstalling the LU  , in this location C:\ProgramData\Symantec\LiveUpdate folder lot of files are there, after reinstalling only one file is showing "LUInstall.Liveupdate" what about other files..

PFA scrren shot , before uninstalling the LU..

At the same time LU is not showing in Add and remove programs also. When I try to ru the LU again am getting Already LU is installed.

We have done the as per the below article , but now luck
