Thanks very much!

I know next to nothing about Windows Command and python. Tried to apply your method and "path-to-py27" is not recognised.

Does it mean that i should put the path to the Python 27 program directory? in what form exactly (on my computer, it is at C:\Python27.

Or does it just mean the path to the directory where the app is already?

I tried without C:\path-to-py27, just typing "reader_archive\reader_archive.py --output-directory C:\mystuff" and got the following response: "Traceback (most recent call last:) File "C:\mihaip-readerisdead set PYTHON_HOME=C:\mihaip-readerisdead\reader_archive\reader_archive.py, line 12, in <module> import base.api ImportError: No module named base.api

Any idea?
