title: Is it possible to upgrade a portable Python 32 bit install to a 64 bit install?
body: <p>I've been working on a single program for a few months now, which now requires some additional functionality. Originally, a 32 bit install was just fine, but since I'm now working with <em>massive</em> matrices in scipy, I simply do not have the required RAM in 32bit. </p>
  
  <p>The other problem I have is that my little project has to be very easily transposeable to new systems belonging to people who have no idea what they're doing and just want to click "run", so I did the whole thing with a portable python install.</p>
  
  <p>Would it be possible to "upgrade" my little 2.7 python to 64 bit, or am I condemned to reinstalling every single module in a fresh install?</p>
