Python's installer tries (and sometimes fails) to install the
KB2999226 update, which installs an old version of the Universal CRT.
Some installers instead bundle the VC++ redistributable, which
includes KB2999226, but that would be overkill for CPython. I thought
we could phase this out in 3.6 to instead require an up-to-date OS. If
people need offline updates, as opposed to using Windows update, it's
better to get the most recent version directly from Microsoft,
KB3118401 . Steve Dower disagreed, and that's the end of it.
As to the loader returning STATUS_INVALID_IMAGE_FORMAT (0xC000007B), I
would run the executable/script under a debugger such as WinDbg or
cdb, with loader snaps enabled via gflags. Find the troublesome
DLL(s), and manually resolve the problem.
