https://forums.autodesk.com/t5/inventor-forum/error-0x80040155-in-ilogic/m-p/5855734#M357700 <P>We tested on several PC with 2013 and no problems. Excel on that PC is working fine. I just disassembled the iLogic code and at that point is calling the Excel Interop. Probably something wrong with the PIA. The point is in Excel 2013 PIA&nbsp;is embedded in the Office setup. No more available as a stand alone installer.</P> Sat, 10 Oct 2015 10:00:37 GMT PiazzaD 2015-10-10T10:00:37Z
