New submission from Steve Dower <steve.do...@python.org>: There's enough instability due to using the proper UCRT installer (e.g. issue25546, issue25954, also others not reported on bpo) and good enough install base that we can simplify things by just installing it locally on machines that require it.
This may also require updating venv (though I think we're fine) and virtualenv (I'll ping). My proposal is to bundle the UCRT redistributable DLLs into their own MSI and install them alongside the main executable when required. If a user later installs it properly, the up-to-date version will be used instead. This should be good enough to cover people still on Windows 7/8, and will also reduce the installer size slightly (though at the cost of potentially breaking non-standard virtual environments or entrypoint stubs that link to the CRT dynamically). ---------- assignee: steve.dower components: Windows messages: 309589 nosy: paul.moore, steve.dower, tim.golden, zach.ware priority: normal severity: normal stage: needs patch status: open title: Change Windows install to applocal UCRT type: enhancement versions: Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32507> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
