John Mayo's referenced post (http://usa.autodesk.com/adsk/servlet/ps/dl/item?siteID=123112&id=13251791&linkID=9240697) could not be located in the Discussion archive. I have a post on the Autodesk EduComm board regarding interoperability of Student version Civil 3D and ESRI ArcMap via widget from ESRI. Is aforementioned reference still available?
Thanks from a newb to the boards. -- Mark

moving my target directory close to c:/ solved the problem...
