The Creo config.pro configuration file is used to automatically set Creo configuration options at startup. A config.pro configuration file can be used with the Creo View Adapter for Creo Parametric, but it must be located in the <setup_directory>. This is because proepublish, proebatch, and proeworker scripts all open Creo from the <setup_directory>. This is also why the trail.txt and log files are in this directory.
