Starting process (one console application from another)

Does anyone knows why I'm getting this error (not every time but sometimes) when trying to start one console application from another. Error:

System.ComponentModel.Win32Exception (0x80004005): Unknown error (0xfffffffe) at System.Diagnostics.Process.StartWithShellExecuteEx(ProcessStartInfo startInfo) at System.Diagnostics.Process.Start()

this is my Code:

System.Diagnostics.Process myProc = new System.Diagnostics.Process();
try
{
    myProc.StartInfo.FileName = @"C:\MyFolder\MyExecutableApplication.exe";
    myProc.Start();
    myProc.WaitForExit();
    procesResult = myProc.ExitCode;
}
catch (Exception ex)
{
    cLog.WriteLog("problem", ex.ToString(), myConfig.LogPath);
}
finally
{
    if (myProc != null)
    {
        myProc.Close();
    }
}

Thank you

I guess it's the permission problem. Try this

myProc.StartInfo.UseShellExecute = false;
myProc.StartInfo.RedirectStandardOutput = true;
myProc.StartInfo.RedirectStandardError = true;

reference from this comments

It seems like an permission elevation problem(although I do not know the reason you get the error sometimes); try adding;

myProc.StartInfo.Verb = "runas";

I faced with the same issue. Try to turn off UAC and add exception to windows defender (or another security tool)
