This document provides tips and tricks using frequently asked questions (FAQs) about the legacy LiveUpdate Administrator Utility (LUAU) 1.x.



Has LiveUpdate Administration Utility 1.x been renamed LiveUpdate Administrator 2.x?
LiveUpdate Administrator 2.x is a completely new web-based program that can centrally manage multiple LiveUpdate servers. Administrators may wish to use this new solution, though the LUAU 1.x remains capable of many functions.

Where can I download the latest version of the legacy LiveUpdate Administration Utility?
The latest version of 1.x, 1.5, is available from: or

Where can I get information about installing and configuring LiveUpdate Administration Utility?

How do I use the username and password fields?
These fields are used by clients only for FTP connections. You will usually use anonymous FTP, meaning that these fields can be left blank.

Note: The username will not be used for LAN connections. If your clients are required to provide a password to access the host folder, LiveUpdate will fail. Further, if you are using Symantec System Center to create the host settings, the password is stored in the registry, and is not encrypted. Do not put a user account and password in these fields.

When would I need a null session share?
A null session share will help resolve LiveUpdate failures when each of the following criteria is met:

  • The client is running Windows 95/98/Me.
  • LiveUpdate is scheduled to run when no user is logged on.
  • The LiveUpdate host is a shared folder on a Windows NT/2000 computer.

For additional instructions, see the document How to create a null session share.

Note: If the client computer is running Windows NT/2000, creating a null share on the server will not have any effect. In this case, you must set up an internal HTTP or FTP server for LiveUpdate.

Why do I see the error message "LiveUpdate is not properly configured to be used with your network"?
This could indicate any of the following problems:

  • The Liveupdt.hst file points to a folder that does not exist or that you do not have permission to view.
  • The folder it points to does not contain all necessary files.
  • When LiveUpdate asks the client how to connect, you are choosing Network instead of Internet. If you are connecting to an internal FTP or HTTP server, choose Internet.

To troubleshoot LAN configurations:

  1. Open your host settings in Symantec System Center or in the LiveUpdate Administrator Host File Editor.
  2. Verify that the type is set to LAN.
  3. Verify that you have a UNC path in the Directory field. It should look similar to this:

  4. Verify the path is correct:
    1. Select the UNC path and press Ctrl+C to copy.
    2. Click Start, and click Run. Delete anything that is on the command line.
    3. Press Ctrl+V to paste the UNC path in the Run box. Click OK.
    4. If you get any errors, you have either not shared the directory, or you did not type the path correctly. Make sure the directory is shared and give everyone at least Read access.

Is there an easy way to find the UNC path?

  1. Click Start, and click Run. Leave this dialog box open.
  2. Double-click Network Neighborhood.
  3. Browse to your shared LiveUpdate folder and drag the folder's icon to the Run line.
  4. You should now see the correct UNC path. Select it, and press Ctrl+C.
  5. Press Ctrl+V to paste the correct path into the Directory field in LiveUpdate Administrator or Symantec System Center.

I have followed the previous steps, so I know that the UNC path is correct, but LiveUpdate still fails. What do I do next?

  1. Go to one of the client computers and ensure that you can browse through Network neighborhood to the shared LiveUpdate folder. You must be able to open this folder without being prompted for a password.
  2. Look at the number of files in that folder. The number of files varies depending on the packages that you downloaded, but if you see less than 5 MB, you may need to delete the AdminSequences key and download the updates again.
    To delete the AdminSequences key:
    Deleting the AdminSequences key will often fix the following problems:
      • When you click Retrieve, only,, and are downloaded.
      • Previously successful client LiveUpdate downloads begin to fail with error messages such as "Unable to retrieve requested file from the server."
      • You have emptied the LiveUpdate Admin Download folder, and you need to retrieve previously downloaded packages again.
    Note: The AdminSequences key is not available on computers running the LiveUpdate 1.6 or 1.7 client.

    To recreate the AdminSequences key:
    1. Using the Registry Editor (regedit), delete the following key:

    2. Click Retrieve to recreate this key and download all current updates.

Why do I get the error "Update not necessary" when launching LiveUpdate from a NAVCE 7.x client.
A fresh installation of older LiveUpdate Administrator Utility versions may not download NAV CE 7 client updates. Once LiveUpdate Administrator has retrieved the updates for any other Symantec product, it will update the available products list to include the NAV CE 7 client.

LiveUpdate only gives the option to connect over a network, but I only have an Internet connection.
You can remove the Network option by deleting the file C:\Program Files\Symantec\LiveUpdate\S32Luhl1.dll.
