https://forums.autodesk.com/t5/inventor-forum/trouble-automating-pack-and-go/m-p/5623235#M376805 <P>I'm trying to automate pack and go with VBA. Following the instructions in the API help file, I create a VBA project and go to Tools &gt; References and try to add Autodesk.PackAndGo.Interop.dll from the Bin folder of the Inventor installation folder. It says "Can't add a reference to the specified file." What am I doing wrong? TIA.</P><P>&nbsp;</P><P>I'm using the VBA editor accessed from an open .idw file by going to Tools &gt; VBA Editor.</P> Wed, 06 May 2015 17:08:20 GMT Anonymous 2015-05-06T17:08:20Z
