Running a python script on C# not working

Question

I have this code that I'm trying to run a Python script. It works correctly when I do it manually via the command prompt but if I try to do it via a button click in a C# Windows form it doesn't work.

private void btnGenerateAndrowarn_Click(object sender, EventArgs e) {
  string[] filePaths = Directory.GetFiles(@"C:\Users\User1\Desktop\Android Tools\androwarn\Samples", "*.apk");
  foreach (string fileName in filePaths) {
    ProcessStartInfo startInfo;
    Process process;
    string directory = @"C:\Users\User1\Desktop\Android Tools\androwarn\";
    string script = "androwarn.py";
    startInfo = new ProcessStartInfo("python");
    startInfo.WorkingDirectory = directory;
    startInfo.Arguments = directory + script + " -i " + fileName + " -r html -v 3";
    startInfo.UseShellExecute = false;
    startInfo.CreateNoWindow = true;
    startInfo.RedirectStandardOutput = true;
    startInfo.RedirectStandardError = true;
    process = new Process();
    process.StartInfo = startInfo;
    process.Start();
  }
}

What do you mean by "doesn't work"? What actually goes wrong? — Katriel, Commented Oct 14, 2012 at 13:58
the script dosn't run at all it should be generating something in my Report folders but nothing happens. If i do it manually it works and generates something in the Report folder. — rexer, Commented Oct 14, 2012 at 13:59
Do you see any error messages in your Output window of Visual Studio when it runs? — Joe L., Commented Oct 14, 2012 at 14:06

Most likely is that python is not in your %PATH%.

But is it in you path when you launch the C# program?
