c# - Opening a pre-existing excel file

I am trying to open a pre-existing excel file from a directory on my computer. However, I am getting a COMexception when my code gets to the Workbooks.Open method. I'm am unsure what I'm dong wrong. Any help is appreciated.

using Microsoft.Office.Interop.Excel;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Excel = Microsoft.Office.Interop.Excel;
using System.Xml;


namespace Excel_Create
{
    class Program
    {

        static void Main(string[] args)
        {


            string mySheet = @"‪‪‪‪C:\Users\Danny\Documents\Visual Studio 2013\Projects\MWS\MWS\bin\Debug\csharp-Excel.xls";

              Excel.Application xlApp = new Excel.Application();
              xlApp.Visible = true;


              if (xlApp == null)
              {
                  MessageBox.Show("Excel is not properly installed!!");
                  return;
              }




         Excel.Workbook xlWorkbook = xlApp.Workbooks.Open(mySheet,
          0, false, 5, "", "", false, Excel.XlPlatform.xlWindows, "",
          true, false, 0, true, false, false              );

        }
    }
}

Here is what the exception says: An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in Excel_Create.exe
