Per your link... The issue with Windows Installer 5.0 is that the SeBackupPrivilege permission is missing altogether. It is necessary to add it to the service permission value in the registry (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msiserver\RequiredPrivileges).
If you use process explorer and look at a system service, you will typically see the SeBackupPrivilege being present, but in the "disabled" state. From my understanding, when the API needs this privilege it enables it, uses it, then disables it again.
