Basically, i wrote a program on Visual Studio that uses Microsoft.Office.Interop.Excel, i added the reference for this directive using NuGet, but i catch this error: 

System.IO.FileNotFoundException: 'Could not load file or assembly 'Microsoft.Office.Interop.Excel, Version=15.0.0.0, Culture=neutral,

Trying to solve the problem, i searched for the Microsoft.Office.Interop.Excel.dll, and add the reference my self using the dll file, but i get the same error.

System.IO.FileNotFoundException: 'Could not load file or assembly 'Microsoft.Office.Interop.Excel, Version=16.0.0.0, Culture=neutral,

I don't know why this error occurs. I've already add the reference to Microsoft Office 16.0 Object, but still the same.

    Hi @Alexandre Dantas , Welcome to Microsoft Q&A,

    In general, if you want to use Microsoft.Office.Interop.Excel, you need to add operations through Com.

    Create a .Net Framework project, add the following to the Reference: User's image

    Just find the excel dll in the com list.

    User's image

    For more information on the use of this dll, please refer to the official documentation: How to access Office interop objects

    Best Regards, Jiale
