Process.Start in C # System cannot find the specified file error

Question

This is a stupid and complicated problem that I have encountered.

The code below works well (it starts the calculator):

ProcessStartInfo psStartInfo = new ProcessStartInfo();
psStartInfo.FileName = @"c:\windows\system32\calc.exe";

Process ps = Process.Start(psStartInfo);

However below for SoundRecorder does not work. This gives me "System error cannot find file."

ProcessStartInfo psStartInfo = new ProcessStartInfo();
psStartInfo.FileName = @"c:\windows\system32\soundrecorder.exe";

Process ps = Process.Start(psStartInfo);

I can start Sound Recorder using the command Start → Run → "c: \ windows \ system32 \ soundrecorder.exe".

Any idea what is going wrong?

I am using C # in Visual Studio 2015 and am using Windows 7.

UPDATE 1 : I tried the check File.Existsand it shows me a MessageBox from the code below:

if (File.Exists(@"c:\windows\system32\soundrecorder.exe"))
{
    ProcessStartInfo psStartInfo = new ProcessStartInfo();
    psStartInfo.FileName = @"c:\windows\system32\soundrecorder.exe";

    Process ps = Process.Start(psStartInfo);
}
else
{
    MessageBox.Show("File not found");
}
