C# - selenium webdriver unable to open chrome browser window

Question

Below is the selenium script to open chrome browser in C# on Windows 10 Visual Studio Code. I'm using Chrome 74 (64 bit) and corresponding ChromeDriver 74.0.3729.6. One thing to note is Chrome is not installed in default directory. This is due to our Office security purpose. It has installed in a different location. When I run the script It gives me error -Failed to create a Chrome process. Could some one please help me to understand why chrome browser isn't opening?

using System;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using NUnit.Framework;
using SeleniumExtras.PageObjects;

namespace NAS
{
    [TestFixture]
    class Program
    {
        public static IWebDriver driver;

        public Program(){}

        [OneTimeSetUp]    
        public void startBrowser()
        {

            ChromeOptions opt = new ChromeOptions();
            opt.BinaryLocation = @"C:\\ProgramData\\Microsoft\\AppV\\Client\\Integration\\520B8677-106E-430B-8927-6F9261C56329\\Root\\VFS\\ProgramFilesX86\\Google\\Chrome\\Application\\";      
            driver = new ChromeDriver(@"C:\\Progra~1\\Selenium",opt);

            driver.Navigate().GoToUrl("http://www.google.com");            
            driver.Manage().Window.Maximize();
        }

        [Test]
        public void testLogin()
        {
            Console.WriteLine("test running..");
        }

        [OneTimeTearDown]
        public void closeBrowser()
        {
            driver.Close();
        }

    }
}

I think your just missing the executable name, like so for example

    var chromeOptions = new ChromeOptions()
    {
        BinaryLocation = "D:\\Chrome\\chrome.exe"
    };
    var driver = new ChromeDriver(chromeOptions);

Thanks for the pointer. After adding executable name I get different error now. Please take a look when you get a moment. Just to let you know I'm not running test as administrator. – Kiran Jul 19 '19 at 09:15
