Unable to open or communicate with Excel and iLogic (Inventor 2013)

[Anonymous]

I'm unable to open or otherwise query an Excel spreadsheet.

I get the following error message.  Please see attached.

What steps must I take to open and query Excel spreadsheets?

I'm using Inventor 2013, Excel 2007 and Vista 64.

Thank you in advance for your assistance!

Hi,

- which version of Excel you installed at your machine?

- which version of Excel API lib you used in your .NET project? If the version is different to the installed Excel, have you make a copy of the Excel API lib (interop) with your dll?
