It installs "OK" but after a scan and updates for it, Live Update gets corrupted with error LU1808.
Anyway, it turns out that the Windows Firewall in XP for each of the clients was blocking these from going through. Once connected, browse to the services section, find the Windows Firewall / ICS service and right-click it. Now that the Windows Firewall is disabled, use the Symantec System Center console to push out the new license file for that PC in question, or a series of PCs.To resolve, just remotely manage the PC in question from the Computer Management console (Right-click My Computer, select Manage). Once done, you can right click the selection of PC’s and update the virus definitions.Be sure to turn the firewalls back on if you happen to use Windows Firewall / Internet connection sharing.This is done in the Configure Definition Update Sources dialog box when you create an antimalware policy.You can configure Configuration Manager software updates to deliver definition updates to client computers.
