Preferring the 64-bit version would be a friendlier experience for
novices in general nowadays. I've had to explain WOW64 file-system
redirection [1] and registry redirection [2] too many times to people
who are using 32-bit Python on 64-bit Windows. I've seen people waste
over a day on this silly problem. They can't imagine that Windows is
basically lying to them.
