Using this sample code :

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using ESRI.ArcGIS.esriSystem;
using ESRI.ArcGIS.Geodatabase;
using ESRI.ArcGIS.Geometry;

namespace Arc_1
{
    public partial class Form1 : Form
    {
        private string path = @D:\ArcObjects\myfGDB.gdb;
        public Form1()
        {
            InitializeComponent();
        }
      
        public static IWorkspace FileGdbWorkspaceFromPath(String path)
        {
            Type factoryType = Type.GetTypeFromProgID("esriDataSourcesGDB.FileGDBWorkspaceFactory");
            IWorkspaceFactory workspaceFactory = (IWorkspaceFactory)Activator.CreateInstance(factoryType);
            return workspaceFactory.OpenFromFile(path, 0);
        }

        private void button1_Click(object sender, EventArgs e)
        {
            FileGdbWorkspaceFromPath(path);
            MessageBox.Show("You are connected now");
        }
    }
}

But I am encountering with this error
Retrieving the COM class factory for component with CLSID {71FE75F0-EA0C-4406-873E-B7D53748AE7E} failed due to the following error: 80040111.

I changed the project .Net framework from 4 to 3.5 client but smae thing still happening!
Can you please let me know why this is happening?
Thanks
