<OpenEdge-install-dir>/bin/showcfg <OpenEdge-install-dir>/progress.cfg

For example:

/userdir/smith/101b/bin/showcfg /userdir/smith/101b/progress.cfg

The SHOWCFG utility displays the product configuration information stored in the OpenEdge configuration file progress.cfg, which is created and modified during product installation.
