Plug in location

Where does Solidworks pull Plug In data from? When installinga plug in application, solidworks picks up what was loaded. Wheredoes this data reside. I'm attempting to get Solidworks to use theSmarteam plug in on a 64 bit OS, but need to make a change to theplug in itself. I need to know where this plug in data is stored.

For instance, if I install CosmoWorks, Smarteam then recognizes itas a plug in. Where is this held?SolidworksEdrawings
