[python-win32] How to call Python methods and properties from VBS?

Hi Mark,
I am aware of the registering issue and the demo listed a path to
pointed to every location where that .DLL or .exe file may be located. It
was as if it got installed everywhere; assuming that both the compiled and
install path of Python is also being shown.
The IE problem is not the problem, for I downloaded the files, not once,
but twice, and each time when using windows to run the .exe file the same
error comes up. It also will ask for a password, yet none of my other
executables I download ask that question. In other words, I am not running
it from IE.
I have downloaded Portable Python because it's packages has all these
packages inside of it. I don't know when I will use that version. But it
sounds like a real good alternative for running Python and all packages.
I am getting back hopefully tomorrow afternoon my Del latest XP computer
which was in repair, rebuilt. That version may open these files but I just
don't think so. My old computer I am using now just has an old version of my
screen reader program and only SP1 of any Windows stuff. Maybe that is the
issue, but that does not explain failure of only these .exe files and none
of my other downloads on different pages of that same web site for Python
downloads. Some difference is some are .sy, but still only these files give
me any grief.
Once I get my better computer back I will experiment with the files and
registering Python as shown. For this computer will not have Python loaded
onto it until I do so and will be able to test to see if it in fact does
work when compiled and registered.
My old computer I have no desire to change anything since it does
compile and things run, but as attempting to update the win32 stuff, it
dies...attempting to install them.
All I can see right now is to compile on the old and run them on the new
as if Python did not exist. Once confident I can do this I will then install
Python, maybe; or use Portable Python.
I guess the question to ask is, have you had any problems with Portable
Python? That's if you have run it.
Sincerely
Bruce

If you built a DLL via py2exe and registered that, then it will not be
using the local installation of Python but a copy of Python which py2exe
has packaged up. That is basically the entire point of py2exe.

A py2exe created package does not need Python installed to work.
However, it also doesn't perform the actual installation - you want
something like nsis or inno for that.

I have heard that internet explorer can get upset with the installation
files for some reason - can you try a different browser? Or even try
and start the installer executable from Windows itself instead of via
IE? FWIW, the files on sourceforge are fine.

The files are hosted on sourceforge and they often redirect you to a
mirror. I'm afraid I'm not sure of what the canonical location of the
"actual download" is, but I'd be very very surprised if one of their
mirrors added a virus.
