The applications, seeking for DSN they looking always the System DSN tab. Once you press add and choose Oracle in OraClient the Oracle ODBC Driver Configuration form will appear.
The only way to configure a connection that doesnt use the default port (1521) is through DSN via TNS Service Name combo.
By default when installing ORACLE CLIENT, creates the ORACLE_HOME and TNS_ADMIN environment variables (aka Control Panel > System > Advanced System Settings > Environment variables button)
Afterall, by going to a windows explorer window and typing %TNS_ADMIN% and pressing enter, you landing to a folder that tnsnames.ora exists, if not create it!
