Error with ChromeDriver.exe when using Coypu for Selenium

I'm making an app, to test this framework unit test. However, it indicates an error that can not find the path where ChromeDriver.exe is, and it is in the folder I indicated.

Here is my code:

using System;
using Coypu;
using Coypu.Drivers;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using NUnit.Framework;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

namespace Coybu
{
[TestFixture]
public class UnitTest1
{
    [Test]
    public void TestMethod1()
    {
        //Aqui indico o caminho onde se encontra o GoogleDrive.exe
        IWebDriver drive = new ChromeDriver("C:/Google");

        var sessionConfig = new SessionConfiguration()
        {
            Browser = Browser.Chrome,
            AppHost = "minhaurl.com",
            Driver = typeof(Coypu.Drivers.Selenium.SeleniumWebDriver)
    };

        var browser = new BrowserSession(sessionConfig);


        browser.Visit("/usuario/login");
    }
}

}
