IronPython Microsoft.Scripting Exception - exception

Question

I am trying to run IronPython code with c#.
I created a simple console application (.net 4) and added IronPython.dll , IronPython.Modules.dll and Microsoft.Scripting and wrote the next code -
using Microsoft.Scripting.Hosting;
namespace app
{
class Program
{
static void Main(string[] args)
{
ScriptRuntime runtime = IronPython.Hosting.Python.CreateRuntime();
ScriptEngine engine = runtime.GetEngine("py");
engine.Execute("print 'hello!'");
}
}
}
While trying to run this , I get an exception -
Unhandled Exception:
System.Reflection.TargetInvocationException:

target of an invocation. --->
System.IO.FileNotFoundException :

Whic version of iron python are you using ? The syntax you show seems belong to an older version, now you should have something like:
var ipy = Python.CreateRuntime();
anyway this blog post seems to be really accurate on pointing the correct reference to use. Anyway, ensure you have the latest IronPython version.
