Logstash Server 2016 Server Issues

I have been trying to install and never get past the error below. I am trying to configure this up to pipe both netflow and system logs to the server. Can anyone help?

Sending Logstash logs to E:/logstash-7.6.1/logs which is now configured via log4j2.properties

I would carefully check your logstash.yml to make sure you have not set "modules.-name", since logstash has not loaded anything that knows how to process that.
