Given. We either download them from various specified sites or newbies 
get a CD when they receive hardware that is used by the sponsor's programs.

Add-Remove would be a very good answer, except for one thing. Understand 
that I'm in Win7 so CP takes on a different form. On Control Panel 
Add-Remove, I can find exactly two Python files: Python 2.5, and 
python-Numpy-1.2.0. No scipy anything. Well, this is interesting. I just 
noticed Martin v. Loewis on the Python 2.5 entry. That's you, right?

msiexec. Don't need it automated now, but it might be worthwhile, at 
some future point.

I think I posted the errors my partner got above. Let me look. Yes,

Here are the first few lines of code.
