I have NAV 2006 running on XP. When I ran Liveupdate I got a message 'Liveupdate was unable to access the file it downloaded'. Reran same result. Checked Symantec and ran recovery as suggested. When I run Liveupdate now I do not get the error message. But when I left click on Liveupdate the status window reads: "The following Symantec products and components are installed on your computer. > LiveUpdate" Would someone tell me if this is correct please as I thought that Antivirus (or something similar) should show up in the list.
