Jeremy Kloth added the comment: After attempting to find the installer for ucrtbased.dll on my dev machine and reading various blog posts on the Visual C++ Team Blog and hunting through several KB articles, I've come across what I think is needed for an up-to-date Universal CRT.
When installing (or in this case modifying) VS2015, the Windows 10 SDK *MUST* also be installed. It is unhelpfully located in the setup menu under "Windows and Web Development" (good) -> "Universal Windows App Development Tools" (not so good) -> "Tools (1.2) and Windows 10 SDK (10.0.10586)". As Python is not an UWP app, I thought nothing of this submenu when installing VS2015 initially. With the SDK installed, my ucrtbased.dll is at version 10.0.10586.15. Now we wait and see if the deadlocking still happens. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26624> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
