I'm a c# newbie so bear with me. I'm trying to call "pslist" from PsTools from a c# app, but I keep getting "The system cannot find the file specified". I thought I read somewhere on google that the exe should be in c:\windows\system32, so I tried that, still nothing. Even trying the full path to c:\windows\system32\PsList.exe is not working. I can open other things like notepad or regedit. Any ideas?

C:\WINDOWS\system32>dir C:\WINDOWS\SYSTEM32\PsList.exe
 Volume in drive C has no label.
 Volume Serial Number is ECC0-70AA

 Directory of C:\WINDOWS\SYSTEM32

    try
    {
        // Start the child process.
        Process p = new Process();
        // Redirect the output stream of the child process.
        p.StartInfo.UseShellExecute = false;
        p.StartInfo.RedirectStandardOutput = true;

        //This works
        //p.StartInfo.FileName = @"C:\WINDOWS\regedit.EXE";

        //This doesn't
        p.StartInfo.FileName = @"C:\WINDOWS\system32\PsList.exe";
        p.Start();

        // Do not wait for the child process to exit before
        // reading to the end of its redirected stream.
        p.WaitForExit();
        // Read the output stream first and then wait.
        s1 = p.StandardOutput.ReadToEnd();
        p.WaitForExit();

    }
    catch (Exception ex)
    {
        Console.WriteLine("Exception Occurred :{0},{1}",
        ex.Message, ex.StackTrace.ToString());
        Console.ReadLine();
