I was quite hesitant about whether I should post this question here on "StackOverflow" or on "SuperUser", but finally decided to post it here as Python is more a programming language rather than a piece of software.

I've been recently using Python 2.5.4 that is installed on my computer, but at the moment I am not at home (and won't be for about two weeks from now), so I need to install the same version of Python on another computer. This computer has Windows XP installed – just like the one that I have at home.

The reason why I need Python 2.5.4 is because I am using “Google App Engine”, and I was told that it only supports Python 2.5

However, when I went to the official Python page for the download, I discovered that certain things have changed, and I don’t quite remember where exactly from that site I had downloaded Python 2.5.4 on my computer at home.

I found this page: http://www.python.org/download/releases/2.5.4/

Here is how it looks:

A few things here are not clear to me.

It says:

For x86 processors: python-2.5.4.msi

For Win64-Itanium users: python-2.5.4.ia64.msi

For Win64-AMD64 users: python-2.5.4.amd64.msi

First of all, I don’t know what processor I am using – whether mine is “x86” or not; and also, I don’t know whether I am an “Win64-Itanium” or an “Win64-AMD64” user. Are Itanium and AMD64 also processors?

Later it says:

Windows XP and later already have MSI; many older machines will already have MSI installed.

I guess, it is my case, but then I am totally puzzled as to which link I should click as it seems now that I don’t need those three previous links (as MSI is already installed on Windows XP), but there is no fourth link provided for those who use “Windows XP” or older machines. Of course, there are these words after that:

Windows users may also be interested in Mark Hammond's win32all package, available from Sourceforge.

but it seems to me that it is something additional rather than the main file.

So, my question is simple: Where in the official Python website I can download Python 2.5.4, precisely, which link I should click?
