PATH or PYTHONPATH under Windows ???

[Stef Mientki]

hello,

after cleaning up a PC, Python can't find any libraries anymore.
But happily I've still one PC, where Python is running perfect.
Now I always read about the environment variable "PYTHONPATH".
But on neither PC there exists a "PYTHONPATH".

On the PC that works ok,
there is the standard "PATH" environment variable,
and indeed there are all the Python Library references.

Please enlighten me.

thanks,
