When I try starting Mastercam Direct from Autodesk Inventor 2013 using the Add-Ins tab, I get the error "Cannot find Mastercam executable". From Inventor's "Environments" tab I selected Manage -> Add-Ins -> Applications, the "Mastercam Direct for Inventor" selection shows Automatic/Loaded and is using for the location value: C:\Program Files\mcamx6\direct\MCInventorAddin.dll. What am I missing that prevents MasterCAM Direct from starting Mastercam X6?.
