Python 2.6 for Windows 64-bit AMD

[dineshv]

I upgraded from Python 2.5.4 to Python 2.6.2 under the Windows 64-bit
AMD version, but no external libraries (eg. pyparsing and Numpy 1.3)
work.  I noticed a few odd things:

i.  pyparsing could not find an entry for Python 2.6.2 in the Wondows
Registry
ii. Python 2.6.2 only allows per-machine installation instead of per-
user and per-machine.

Can anyone shed any light on what's up with this build of Python
2.6.2?
