SEPM 12.1.2015.2015 with LU Administrator 2.3.2.99 Latest on Manager not update

Hi everyone

I have SEPM and LU Administrator in same host but my Windows Definitions on SEPM doesn't update since 10 april 2014

I was manually donwload liveupdate content at Admin->Servers->Local Site, but it say "LiveUpdate failed" like attached file

I see it call LUALL.exe process to run but I can't found LUALL.exe in host and I know from symantec forum at https://www-secure.symantec.com/connect/forums/windows-cant-find-luallexe-after-migration the luall.exe no longer work with SEPM 12.1

In normally all SEP Clients will update Definition from SEPM, now I temporary solve by let them update from Internet LU.

Then how to fix it. any advice?

Thank in advance.
