Sorry, I don't know of an Inno installer for any version of Python. Because there was a minor (but endless) stream of complaints that building the Python Windows installer required Wise, I checked in the "most of the way there, at the time" .iss file so that someone else could volunteer to finish it. Since nobody cared enough to do so, I ignored such complaints ever after <wink>.
I think that occurred right about the same time that Wise donated the more up to date version of their package. Thus the existing Python installer no longer generated (ignoreable) errors under NT, for example, and was brought up to date presentation wise, so that pretty much resolved the complaints. At least that definitely did it for me, and I had been looking at finishing the file at the time. -- David
