I build project with video

Imports Microsoft.DirectX.AudioVideoPlayback

when developing I can play video why in the client video cannot played?


I get this error in client:

"Unhandled exception has occurred in your application. If you click Continue. the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.
Mixed mode assembly is built against version 'v1.1.4332' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information."

not all client get this error, a few client can play the video a few client cannot play the video

anybody tell me what's wrong?

What I have tried:

Private Sub PlayVideo()
        Try
            If System.IO.File.Exists(file) = True Then
                videoFile = New AudioVideoPlayback.Video(file)
                videoFile.Owner = pnlVideo
                videoFile.Play()
            Else
                pnlVideo.Visible = False
            End If
        Catch ex As Exception
            pnlVideo.Visible = False
        End Try
    End Sub
