INFO: Python on 64-bit Vista

This article explains how to get Python working with XSI on 64-bit Vista systems.

It also applies to XP 64, but #2 and #7 about the "UAC" can be ignored then...

Note that you must use Python 2.6, because on 64-bit Vista, XSI cannot support older versions of Python.

Download PythonInstall64.rar (http://images.autodesk.com/adsk/files/pythoninstall64.rar).
PythonInstall64.rar contains the files required to install Python 2.6 and pywin32 for both Intel and AMD 64-bit processor.

Add the python folder installation (e.g. C:\python26) to the PATH environment variable as the installer won't do it by default. (A short HOWTO can be found on this page: Python to PATH (http://softimage.wiki.softimage.com/index.php/Python_to_PATH))
