[Python.NET] Initial Script Directory?

[Michael Reitzenstein]

I have almost finished my first full project using .Net & Python, however 
when trying the program out on other computers I have hit a problem when 
importing modules.

I couldn't figure out how to set the directory that Python should search to 
import modules when I first started integrating Python into my application, 
so I did a kludge-y method where I copied the script into the program's 
main directory, ran it, and then deleted the script and its compiled 
equivalent once it had been ran. This works fine on my machine - but I sent 
it to my friend to test out, and it wouldn't work. The scripts would copy 
over fine into the program's main directory, but an exception would be 
tripped when attempting to import the module.

I am guessing that the directory that Python searches in is incorrect (not 
defined?) on their machine. I attempted the following at the very start of 
my program:

string Dir = System.Windows.Forms.Application.ExecutablePath;
System.Environment.CurrentDirectory = Dir.Replace( "Buildmeister.exe", "" );
ProgramDir = System.Environment.CurrentDirectory;
			
Python.Runtime.PythonEngine.Initialize( );
Python.Runtime.PythonEngine.RunSimpleString( "sys.path[ 0 ] = '" + 
ProgramDir + "'" );
Python.Runtime.PythonEngine.RunSimpleString( "chdir( '" + ProgramDir + "'" );

...But it doesn't work! Is there any simple way to set the directory that 
python searches for modules?
