Symantec Endpoint Protection Manager 12.1 is not updating 32-bit or 64-bit virus definitions due to corrupt content

Try it

The Symantec Endpoint Protection Manager does not update virus definitions successfully through LiveUpdate

Where is the location of LiveUpdate Log file Log.liveupdate?

LiveUpdate and content troubleshooting for the Symantec Endpoint Protection Manager

LiveUpdate fails on the Symantec Endpoint Protection Manager with errors in Log.LiveUpdate similar to "LiveUpdate couldn't expand replacement path [spcIronWl-incr-InstallDir]."

"Error: LiveUpdate encountered one or more errors. Return code = 4" in LiveUpdate status in Symantec Endpoint Protection Manager

Windows 2008: C:\ProgramData\Symantec\LiveUpdate

Hi,

When you run LiveUpdate manually with LUALL.exe command, what exactly happen ?

Is your SEPM able to connect to LiveUpdate servers and download the contents or not ?

Depending if it's connection/download issue or post process into the SEPM Database, we need to gather the Log.LiveUpdate if it's simply connection/download issue.

If it's a post process issue after the downloads of the contents have been successufully done then Sesm-Lu-0.log is needed to point out the root cause.

SemsLu log is located by default on %\Symantec Endpoint Protection Manager\tomcat\logs\

Kind regards,
