I'm not entirely sure about Windows, but my guess is that your problem is
that the pythonpath isn't what you need to set. I would venture to guess
that it's searching for test.py in your current path. If I'm correct in my
thinking, all it does when you set the python path is tells python to
execute in that directory, so if your script contains something like f =
open("myfile.txt", "w") it will put it in that directory.

You may want to try this:

The path is now managed by Windows 2000 / Windows XP and not the
autoexec.bat or autoexec.nt files. To change the system environment
variables, follow the below steps.

   1. From the desktop <http://www.computerhope.com/jargon/d/desktop.htm>,
   right-click My Computer and click properties.
   2. In the System Properties
window<http://www.computerhope.com/jargon/w/window.htm>,
   click on the Advanced tab <http://www.computerhope.com/jargon/t/tab.htm>.
   3. In the Advanced section, click the Environment Variables
button<http://www.computerhope.com/jargon/p/pushbutt.htm>
   .
   4. Finally, in the Environment Variables window, highlight the path
   variable in the Systems Variable section and click edit. Add or modify the
   path lines with the paths you wish the computer to access. Each different
   directory is separated with a semicolon as shown below.

   C:\Program Files;C:\Winnt;C:\Winnt\System32

Try adding the path to your code in that way, and see if it works. HTH,
