Steve Dower added the comment: This is a problem with 3.5 and later running on Windows 8.1 or earlier without all Windows Updates being installed.
It can happen for two reasons: * not using the official installer (most common) * random failure in the official installer (rare) Installing KB2999226 is a good start, though it will likely trigger another Windows Update to get the latest version. Windows 10 is not affected. I'm in favor of adding this to the FAQ. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue31427> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
