You have scheduled definition updates using LiveUpdate for SMSMSE but definitions are not staying up to date.


LiveUpdate works when run as Administrator:

1. Open Windows Explorer and right click c:\Program Files (x86)\Symantec\LiveUpdate\LUALL.exe and select Run as administrator. If a prompt appears select Allow.
2. If the session now completes successfully then this condition is met.






If you run LiveUpdate manually LiveUpdate returns error LU1845: "This product was not updated due to a processing error".


  • Windows 2008
  • User Account Control is Enabled


Windows 2008 UAC is preventing the default account from running LiveUpdate successfully.



Configure LUALL.EXE to always run with Administrator permissions.

    1. Open Windows Explorer and right-click C:\Program Files (x86)\Symantec\LiveUpdate\LUALL.EXE and select Properties.
    2. Click the Compatibility tab.
    3. Under Privilege level check the box next to Run as administrator.
