Im trying to play a video avi file from my hard disk but getting FileLoadException error why?

Question

This is my code in Form1:

private void play()
        {
            pictureBox1.Load(vp.PlayVideoFile(@"D:\testdata\new.avi"));
        }

vp is a variable of my VideoPlayer class:

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

namespace ScreenVideoRecorder
{
    class VideoPlayer
    {
        public VideoPlayer()
        {
        }

        public string PlayVideoFile(string fileName)
        {
            //create the video
            Microsoft.DirectX.AudioVideoPlayback.Video video = new Microsoft.DirectX.AudioVideoPlayback.Video(fileName);
            //Play the video (put this in a buttons click event)
            video.Play();
            //Pause the video (put this in a buttons click event)
            video.Pause();
            //Stop the video (put this in a buttons click event)
            video.Stop();

            return fileName;
        }
    }
}

Why im getting this exception ?

Mixed mode assembly is built against version 'v1.1.4322' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information

What additional configuration information does it need ? And how to do it ?

System.IO.FileLoadException was unhandled
  HResult=-2146232799

Now im getting an exception in my VideoPlayer class on the line:

Microsoft.DirectX.AudioVideoPlayback.Video video = new Microsoft.DirectX.AudioVideoPlayback.Video(fileName);

The exception is: Loader lock was detected :

DLL 'C:\WINDOWS\assembly\GAC\Microsoft.DirectX\1.0.2902.0__31bf3856ad364e35\Microsoft.DirectX.dll' is attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang.

Did you try to add VC++ runtime DLLs, Also .Net is not backward compatible you need to install the right .Net Version :( — Mahmoud Fayez, Apr 12 '13 at 11:16

Add an app.config file to your project with the following content:

 <?xml version="1.0"?>
 <configuration>
   <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v1.0"/>
    <supportedRuntime version="v4.0"/>
  </startup>
 </configuration>

I have downloaded it. I tried to install the directx june 2010 but in the end of the installation it said failed. And the dll wasnt there so i downloaded it. And im using windows 8 64bit and vidusal studio 2012 pro and my project is on .net 4.0 – Ben Kochavi Apr 12 '13 at 11:28
Can you copy the url? Maybe there is a 4.0 version from this. – laszlokiss88 Apr 12 '13 at 11:30
Have you installed the DirectX Software DevKit? http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=10084 (Maybe you should reference the dll from this.) – laszlokiss88 Apr 12 '13 at 11:32
This is the link of where i downloaded the file. I clicked on the green bar Download Now. http://www.dllme.com/dll/files/microsoft_directx_audiovideoplaybac.html – Ben Kochavi Apr 12 '13 at 11:33
Maybe i will try to install again but as i mentioned before in my question or here in comments i tried to install the directx sdk it was installing and just in the end it says Failed. And in the installed directory i saw that many files are missing including this needed dll. But i will try to install it again. – Ben Kochavi Apr 12 '13 at 11:34
