Class not registered exception - SharePoint 2013

Hi All,

We got below error when trying to use SPSecurity.RunWithElevatedPrivileges in console application

Retrieving the COM class factory for component with CLSID {BDEADF26-C265-11D0-BCED-00A0C90AB50F} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

The code is shown below:

using Microsoft.SharePoint;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SampleComnsoleApp
{
    class Program
    {
        
        static void Main(string[] args)
        {
            bool quiet = false;
            SPSecurity.RunWithElevatedPrivileges(delegate()
            {
                (new Program()).Run(quiet);
            });
        }
        private void Run(bool quiet)
        {

        }
    }
}

Resolution:
The console application is running under 32 bit processor. Just change it to 64 bit.
To do this:

• Right click on Console Application
• Select Properties 
• Under Build Tab, change Platform Target to x64
• Rerun the application and hopefully the error should go away now !
