KB950130, KB951338, KB951944, KB951596, KB954326, KB956080, KB951546
Examing the %systemroot%\Temp\MSI*.log files revealed that the admin account did not have access to the registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\Uninstall\ENTERPRISER
Giving the administrators group and the system account ownership and Full Control of the registry key resolve the update issues.
