I'm trying to get access to my Excel document using the Interop in .NET. But Unity keeps giving me this error
--
> Assembly 'Assets/Plugins/Microsoft.Office.Interop.Excel.dll' will not be loaded due to errors:>>Unable to resolve reference 'office'. Is the assembly missing or incompatible with the current platform?

1. I copied the Microsoft.Office.Interop.Excel.dll file from *C:\Program Files\Microsoft Office\root\vfs\ProgramFilesX86\Microsoft Office\Office16\DCF* into my *Assets\Plugins* folder in my project.
2. I select the .dll file in the Project pa**nel and in the Inspector I tell it to only run in the Editor on x86_64 and Windows**.
3. The Inspector tells me **Assembly Info Targets .NET 4.x**, so in the **Player settings** I set **Scripting Runtime Version** to **.NET 4.x Equivalent**, **Scripting Backend** to **Mono** (or IL2CPP, none of them work), and **Api Compatibility Level** to **.NET 4.x**. In the **Build settings** I have selected **Windwos x86_64**.
4. In Visual Studio Microsoft.Office.Interop.Excel is automatically added as a reference by Unity and I don't get any errors in Visual Studio, InteliSense and syntax highlight is working as expected. Visual Studio confirms that this is version 16.
5. Software used: Unity 2019.1.14, Visual Studio 2017, Windows 10, Office 365 desktop softwares installed on computer.

What is the problem? Why doesn't it work and why can't Unity resolve the reference Microsoft.Office when Visual Studio clearly can do it? Why isn't this working?
