Can't instantiate a COM object written in C# from VBA (VB6 ok)

Question

Using VS 2008, here is my COM object

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
using System.Wi         


        

Answer 1

I'm going to answer my own question, hopefully to spare others the hours of tedious drudgery I have just endured.

If you get this, it is because the .NET based COM assembly can't find the .NET framework

The solution is simple. Create a file containing the following

Call it "Excel.Exe.Config" and place it in the same directory as "EXCEL.EXE"

Problem solved!
