Request please do not copy logs from the console, instead send log files. See OWS Guide for logging.

Also request you to buy support for guaranteed response to your posts on the forum and to enable us to maintain OWS opensource project.

In the OWS install dir "Command+Shift+." will show hidden directory ".install4j". You will find "response.varfile" there.

should be

I cannot say why OWS does not work without knowing about your environment.

For guaranteed response I would request you to buy support https://openwebstart.com/#supportoptions
