Connecting Windchill Workgroup Manager to Creo Illustrate

My company recently started using Creo Illustrate.  So far I have been unsuccessful in connecting Windchill Workgroup Manager to Illustrate.  Is there somewhere I can download WWM?  Wasn't able to find a link on the PTC site.  Do I already have WWM if my Creo Parametric is able to access Windchill?  Any help would be appreciated.
