This error has been seen to occur upon a corrupt installation of service pack 6. Uninstall and reinstall the 2.1i Foundation / Alliance software, then reinstall service pack 6. Ensure that other applications are closed when installing the service packs. Also note that at least 200MB of temp disk space must be available.
