I regularly test whether it installs properly into Program Files
(although regularly actually means "for every major release"). Also,
users regularly report if it doesn't work.
As it turns out, 3.4 indeed got a new problem when installing into
Program Files, namely that pip would not install. As discussed elsewhere
in this thread, installation into Program Files requires elevated
privileges, which meant that I had to reschedule the pip installation
procedure within the MSI to run in the system context.

I expect breakage elsewhere (as also discussed):
- some code will fail because of the space in the path
- some installations will fail because of the restricted access to
Program Files (which, of course, is also the main reason why people
want that install location)
It's of course now up to Steve to rule on the default install location;
if he changes it, he will get lots of both praise and blame, if he
doesn't change it, he will get a little blame for continuing the
