  • Hello,

    Sometimes after installing they will not show up in the list of references. You can use the browse button and traverse to where Interop.Excel was installed.

    The following is a sample path which may be different on your computer but it will get you in the right direction.

    C:\Program Files (x86)\Microsoft Visual Studio 12.0\Visual Studio Tools for Office\PIA\Office15

  • Is Excel, or Office installed on your PC?

    As far as I know you can only have Interop.Excel with the Excel installation.

  • Have you visited the Extensions node in the Add Reference dialog too?

  • Which version of Office do you have installed? The Office PIA are generally installed when Visual Studio is installed. Some of the older versions are downloadable but newer versions are not. See the below links for more info:

    Office Primary Interop Assemblies

    Microsoft Office 2010: Primary Interop Assemblies Redistributable

    BTW, make sure the Embed Interop Types property for your PIA is set to True so that deployment of the interop assemblies is not required and also to enable support for multiple versions of Office.

  • Hi Muljanto,

    There is no need to download Interop assembly from .net, you can just go to add reference and browse to

    C:\Windows\assembly\GAC_MSIL\Microsoft.Office.Interop.Excel\ for Visual Studio 2015.
