There's a note regarding a parameter that is required when installing on Unix or Linux if you include the examples.
If that doesn't help, then maybe you can add the -log=full_path_to_log_file and review the log. It works with a windows install, not sure if it works for a Unix install, but it wouldn't hurt to try. If it doesn't work, check the logs directory in your middleware home to see if an install log is created by default.
