C # code could not be called from vbscript - ActiveX error

I am trying to call a method that I wrote in C # from VBScript.

I have followed almost all the instructions that I can find on the Internet and am still having problems.

In particular, I get

Error: ActiveX component cannot create object

Code: 800A01AD

So far I have done the following:

  • Install ComVisible(true)
  • Registered with regasm /codebase
  • Strongly called my assembly
  • It is confirmed that it is in the registry and indicates the correct location.
  • Created a class public
  • No static methods
  • Made a method that I want to call public
  • Has a constructor without parameters
  • Explicitly defined GUID

My VBScript looks like this:

set oObject = CreateObject("TTTTTT.FFFFF.CCCCCCCCC")

My C # code is as follows:

using System;
using System.IO;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace XXXXX.YYYYY
{
    [ComVisible(true)]
    [Guid("3EB62C37-79BC-44f7-AFBD-7B8113D1FD4F")]
    [ProgId("TTTTTT.FFFFF.CCCCCCCCC")]
    public class CCCCCCCCC
    {
        public void MyFunc()
        {
            //
        }
    }
}

Can anyone help?
