LiveUpdate Stopped Working on SEPM with return code = 2

I came to know that our SEPM server was not updated for last 7 days and showing old virus definition version on home screen. I did some normal stuff to update SEPM but none of them helped. Every time i try to update it i was getting error messages as per below attached screenshot.

While troubleshooting, i found that LUALL.exe is not available and LiveUpdate is also not showing in "Programs And Features" in control panel. And Return Code = 2 is also saying about Live Update. So after more dig in it, i fixed it, below i am going to share all steps which i performed.

Fix:

Step 1 : Navigate to C:\ProgramData\Symantec\LiveUpdate\ and delete all files and folders from it.

Step 2 : If you a setup folder of your SEPM. Then Navigate to *\SEPM\ and run LUCHECK.EXE (It will check about every thing for LiveUpdate and install it.)

Step 3 : Registered install Live Update with SEPM. Open Command Prompt and type "lucatalog.exe -forcedupdate" for SEPM 12.1+ and "lucatalog.exe -update" for SEPM 11.1+. Now, Hit Enter. It will register it.

Step 4 : Open SEPM and Run Live Update again.

Thank You
