We recently upgraded to Solidworks 2015 & EPDM 2015 and we are getting this error on one pc. The others are working fine.
Usually this error occurs when the user don't have in local cache (in EPDM) swbrowser.madb. "Get latest version" on toolbox folder in EPDM system.
Hope this helps
Both answerers are correct. I needed to do a "get latest" and set the path to the correct location.
