I take it you have business reasons to use an obsolete version python.
Where did you get your version of python from?

You seem to be doing the right thing with setting an environment variable.
Useless shades is an app that embeds python.

Try starting cmd.exe and using the set command to liat all of the environment.
Do you see your PYTHONPATH variable?
Does it contain what you expect?
If it does start python and check that sys.path has your folder in it.
Also check what is on os.environ dirctionary.

One can't proceed from the informal to the formal by formal means.
