In order to be able to "execute" scripts via the command prompt,
batch files, system(), subprocess.Popen() or similar, the extension
must be associated with an interpreter in the registry. This cannot be
overridden via environment variables.

Note that Python 3 includes a launcher utility for Windows:

	http://docs.python.org/3/using/windows.html#launcher

The idea is that the .py extension can be associated with the
launcher, which can be configured to use a specific version of Python
in a specific context.

I don't know whether it's possible to make use of this without
installing the rest of Python 3, though.
