Ran into an issue today where Symantec's Live Update was not showing up an installed application on a backup server. I confirmed this as my attempt to run Live Update via Backup Exec pulled up this message:

Here's a quick way to get Live Update back on the server, so you can run updates to keep Backup Exec up to date:

1. Go here <a href="ftp://ftp.symantec.com/public/english_us_canada/liveupdate/3.3.0/LUSETUP.EXE">LiveUpdate3.3</a>

2. Download the program to a safe place

3. Run the program and you should get a "<strong>Live Update Installed Successfully</strong>" message

4. Re-open Symantec Backup Exec, click Tools, Live Update

5. And you should be all set with the Live Update Tool moving forward.
