Zerotouch Using Microsoft.Office.Interop.Excel.dll

In my zerotouch project I am referencing “Microsoft.Office.Interop.Excel.dll” in order to utilize some Excel functionality with C#. If I am using the reference, the node will not appear in my dynamo workspace but if I remove it, everything else works fine. I’ve tried adding the .dll in the bin folder of my node as well as publishing locally with the Excel .dll included, however to no avail. Can someone more knowledgeable shed some light on how to make a node referencing methods of the Microsoft.Office.Interop.Excel.dll work? Thank you.

I think it could be related without any other info.


Hey Michael,

Thank you for pointing me to the right direction. I was playing around with changing property values from True to False but of course it was the one property I didn’t mess with. Haven’t fully tested it out yet but it looks good so far.
