A collaborator installed the Oracle Web Conferencing console, but can't start it when joining a web conference. He gets an error "RTCC024". I can't find any such code on Oracle's own Technology Network. On the whole Internet I found only [one Ubuntu post in Portugese|http://ubuntuforum-pt.org/index.php?topic=10133.0] (?) and that contains no solution or additional information either. Can anybody tell me what problem generates this error? The user has a PC running Windows XP, MSIE.
