You need to manually uninstall LiveUpdate Administrator (LUA) 2.1 or later, or you see "Error 1720. There is a problem with this Windows Installer Package" when removing LUA through Control Panel.
Windows Installer is corrupt on the affected computer.
If using the Windows Add/Remove Programs does not work when uninstalling Live Update Administrator, delete the following registry entries and file/folder locations after stopping the program's services:
cmd
net stop “LUA Apache Tomcat”
net stop “LUA PostgreSQL”
Most of the items that you must remove are entries in the Windows registry.
Note: You must have administrator permissions (read and write) to edit the registry.
WARNING: In the next steps you will edit the Windows registry. Back up the registry before you make any changes to it, because incorrect changes to the registry can result in permanent data loss or corrupted files. Modify only the registry keys that are specified.
regedit

After Symantec LiveUpdate Administrator is disabled, you need to remove leftover files to the program.
This completely removes LUA from the affected computer.
