Why I get "PermissionError: [WinError 5] Access is denied" error when I using youtube-dl in c# process class?

Question

when I run youtube-dl.exe with c# process class on server, it returns below error in StandardOutput:

Traceback (most recent call last):
  File "__main__.py", line 19, in <module>
  File "C:\Users\dst\AppData\Roaming\Build archive\youtube-dl\rg3\tmpc7h_sle1\build\youtube_dl\__init__.py", line 449, in main

  File "C:\Python\Python34\lib\ssl.py", line 377, in _load_windows_store_certs
PermissionError: [WinError 5] Access is denied

What is these errors?I don't have these paths and files with these directories. And Here is my code

   string ydlPath = Server.MapPath("/ydlPath/youtube-dl.exe");
    string tempLocation = Server.MapPath("/ydlPath/");

    System.IO.StreamReader errorreader;
    System.Diagnostics.Process proc = new System.Diagnostics.Process();
    proc.EnableRaisingEvents = false;
    proc.StartInfo.ErrorDialog = false;
    proc.StartInfo.RedirectStandardError = true;
    proc.StartInfo.FileName = ydlPath ;
    //proc.StartInfo.Arguments = "-F \"" + Url + "\"";
    proc.StartInfo.WorkingDirectory = tempLocation;
    proc.StartInfo.Arguments = "-f bestvideo[ext=mp4]+bestaudio[ext=m4a] \"" + Url + "\"";
    proc.StartInfo.Verb = "runas";
    proc.StartInfo.UseShellExecute = false;
    proc.StartInfo.CreateNoWindow = false;
    proc.StartInfo.RedirectStandardOutput = true;
    proc.Start();
    errorreader = proc.StandardError;
    string Output = proc.StandardOutput.ReadToEnd();

    proc.WaitForExit();
    proc.Close();

I used this on my local and it works fine. Also when I use youtube-dl.exe with cmd on server or on my local I don't have problem.

How can I solve this problem? Anyone can help me?

Because access to the path you're trying to access is denied — Sami Kuhmonen, Sep 25 '16 at 09:15
@SamiKuhmonen yes I think. root folder have iis and administrator permissions — Parsa Saei, Sep 25 '16 at 09:23

@YenChiHsuan,I have a question.with this compressed python version,I can't download from somelinks,but with exe version it's work.what is the reason of this? – Parsa Saei Oct 16 '16 at 10:24
A possible reason is that the two files are based on different youtube-dl versions. – Chih-Hsuan Yen Oct 16 '16 at 16:08
@YenChiHsuan How can I handle it?can I? – Parsa Saei Oct 17 '16 at 06:01
Hi parsa, I guess you've opened https://github.com/rg3/youtube-dl/issues/10766? Could you move to Github for further discussions? Commenting on Stackoverflow is not as convenient. – Chih-Hsuan Yen Oct 17 '16 at 16:51
@YenChiHsuan Ok – Parsa Saei Oct 18 '16 at 06:22
