Import Excel library to VB.NET in Visual Studio

Question

In a Web project in VB.NET in Visual Studio I performed the import of a library to generate Excel files. (In the Tools menu --> Extensions and Updates).

I made the import on the desired page (Imports Excel = Microsoft.Office.Interop.Excel) and managed to use it normally and correctly.

However, when sending my project to the server (Build --> Publish Project Name), the system is updated correctly, without errors, but the library does not work in the online version of my system. The button that should generate the file . xlsx, which works locally, in the online version does not work.

Any idea that might help me?
