    I have the exact same problem. I about to just uninstall and go to a different program.

  12. thelle7 Says:

    Try turning off Windows firewall. I did not have this issue with any of my Windows XP machines, only my Vista boxes. Once I turned it off, it worked fine.

    If you have another firewall program, try turning that off or disabling it as well.

  13. Rob Says:

    Clearing the live update cache fixed the issue for me.

    Narayanan’s solution fixes it completely! checked another settings.liveupdate file and it doesnt even have the timeout settings which leads to the assumption that.. watever,

    USE NARAYANANs SOLUTION PEOPLE!!!

  19. Hisham AL-Zuhd Says:

    This problem may occure because of the work day load on the internet line of your org.
    note :esp. when using firewall.

  22. uDAY Says:

    i COULD ABLE TO FIND THE LOCATION OF FILE TO CHANGE THE SETTING BUT NOT ABLE TO EDIT IN THE SETTING OF FILE FROM 45 TO 120 AS PER NARAYANAN SOLUTION. iT DOES NOT ALLOW ME TO SAVE THE CHANGES


  23. uDay it is easy to fix this. In the Liveupdate folder, right click setting.liveupdate and select Properties. Uncheck the ‘Read Only’ box and click Apply. You can now save the file again – remember to change the permission back to ‘Read Only’ and clicking ‘Apply’ again.

  24. Computer challenged =) Says:

    Can someone describe in more detail how to locate the setting.liveupdate file, how to open it, how to save it etc. I’ve tried to open it with Word, but it won’t let me save it in the same location…
    I don’t know much about computers, so the simpler, the better. I’m having trouble with the LU1835 time-out message and would love to know how exactly to increase the default time-out. Please help! Thanks so much!

  25. Francisco Says:

    The liveupdate.settings file also has records for HOST which seem to also point to what may be old corporate liveupdate servers. Find a computer that has working settings and replace the lines beginning with HOST from that file into the file on the system with the issue. That resolved my issues with this error.

  26. ATlien Says:

    The issue is caused by your firewall. I had the same problem for nearly two weeks.

    Increasing the timeout allows your firewall more time to scan the packets from the live update server.

    Another solution is to whitelist or write an exception for outbound traffic from your server’s IP address.

  27. metalheadkicks Says:

    I solved this problem following Narayanan’s method recently. But he forgot to mention you have to disable norton identity safe and Symprotect Tamper Protection (norton settings) before editing the setting.liveupdate file and changing it to a higher value.

  28. Marcus Says:

    I had this issue but none of the above advice provided resolution. It turned out that the LiveUpdate cache was set to 10MB whilst I was trying to download 50MB of updates hence the failure. You can modify the size of the cache in the LiveUpdate applet in Control Panel.
    Hope this helps.

  29. Sima Says:

    none of the above solutions can help me,,, I increase the live update timeout to 240,,, but no help,,,
    I still have this problem (Error:LU1835) at my both computer,,
    one of them is Windows7+Symantec Endpoint Protection v.11.04202.75,,, and another is WindowsXP+Symantec Endpoint Protection v.11.04202.75

  30. SUDHAKAR Says:

    NOT THIS ONLY ANY SYMANTEC PRODUCT NO SOLUTION
    ITS WASTE OF MONEY

  31. LiveUpdater Says:

    So i figured out what it was. Go to LUConfig.exe in the LiveUpdate folder under C:\Program Files (x86)\Symantec and change the cache size from 10MB to something large 2(I did 2GB). This should help since the first time there may be a ton of updates to download.

  32. LiveUpdater Says:

    correction, it was a COMBINATION of issues. the cache size, the update timeout, and the firewall being on.

  33. tcs Says:

    hi am having a live update issue on symantec endpoint v11.
    has anyone solved this. i have been doing manual updates on the machines but its too much.

  34. Devanarayanan Says:

    It is essentaial that my PC should be free of viruses. I know that LU 1835 is the only safe update one can think of for safeguarding the PC.

  35. Palani Says:

    Uncheck the read only option from setting.liveupdate and then able to install live update in the interactive mode.
    check the modify date of setting.liveupdate file and open it with notepad.
