[New-bugs-announce] [issue1543] MSI installer needs to be updated to install x86 and x64 versions of Python on Vista 64 bit

[Isaul Vargas]

New submission from Isaul Vargas:

Problem:
I'd like to run Python 32 bit (for compatibility with extensions) and 
Python 64 bit on Vista (for speed and 64 bit apps) on one machine. 
However Vista has an 'improved' installer for MSI apps, where if I 
install Python 64 bit first, I can't install Python 32 bit afterwards, 
because Vista's Window Installer says 'Another version of this product 
is already installed. Installation of this version cannot continue. To 
configure or remove the existing version of this product, use 
Add/Remove Programs on the Control Panel'

The converse of this is true, if you install Python 64 bit first, you 
cannot install Python 32 bit afterwards.

The MSI packaging needs to be updated.
