up

It could be MS Installer problem on that particular server. You can try install something else and see if there will be problem with install too.
You can also try to check HKLM\Software\Policies\Microsoft\Windows\Installer, if "DisableMSI" is set to "2". For MSInstaller to work it must be set to "0"

What does the other return value 3 say?

Just as a heads up, Did you ever have AMS on this server. If it's still visible in the add\remove programs.
