New submission from Raymond Hettinger <raymond.hettinger at gmail.com>:

On the downloader page, http://www.python.org/download/releases/2.7.2/ there is an entry "•Windows X86-64 MSI Installer" that links to http://www.python.org/ftp/python/2.7.2/python-2.7.2.amd64.msi

Running this installer succeeds and show messages that a 64-bit version of Python is being installed; however, running Python shows that only a 32-bit version is being run despite a welcome message stating that a 64-bit version is being run:

Python 2.7.2 (default, Jun 12 2011, 14:24:46) [MSC v.1500 64 bit (AMD64)] on win
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.maxint
