Python-2.3.5.exe seems to be corrupt.
I’ve tried downloading Python-2.3.5.exe a number of times in the past week, and so have a few of my colleagues. It always transfers in an incomplete manner, resulting in only 4.7 out of 9.1 MB. I have tried from several different Windows 7 boxes, with the same results.

Perhaps something in my environment is messed up, but it may be that the file is corrupt on your server.

I tried to download it on a win xp machine and I succeeded at the first attempt (even thought it seemed to be stuck for a few seconds before reaching 100%).  I was also able to start the installer, even thought I didn't install it.
This is the version I downloaded: http://www.python.org/ftp/python/2.3.5/Python-2.3.5.exe

May I ask you why you are attempting to download such an old release, and not even the latest 2.3 (there's 2.3.7 available, that also includes some security fixes)?

Ezio,

It is what was in use on my old machine, and I don't want to move versions.

Thanks,
Jeff

I'm getting the complete file here, too.
