Default Behavior

The Windows Installer service runs as LocalSystem in its own process. It does not share an executable file with other services. If the Windows Installer fails to load or initialize, the error is recorded into the Event Log. Windows 7 startup should proceed, but a message box is displayed informing you that the msiserver service has failed to start.

Dependencies

Windows Installer will not start, if the Remote Procedure Call (RPC) service is stopped or disabled.
