Steve Dower added the comment: In thinking about this, I think the best way forward is to just remove the logic that might statically link the initialization code, and instead commit to CPython releases always including vcruntime140.dll even if we switch to a newer version one day. Hopefull

Steve Dower added the comment: Hmm, just ran it on my own and it's finding the OneCore file first, which is not a problem (yet) but could become one. So we at least need to replace the "**" with a "*" in Lib/distutils/_msvccompiler.py#L109. Not sure if that will help in this other case or n

Steve Dower added the comment: Thanks, it does seem like it's finding the correct MSVC, but is not finding the redistributable DLL: > cl.exe /c /nologo /Ox /W3 /GL /DNDEBUG /MT ... The "/MT" means to statically the CRT, and then we use link settings later to dynamically link the part instal

Xinfa Zhu added the comment: I have had wheel installed. Following this SO answer (https://stackoverflow.com/a/50314071/7269441), I added "import setuptools" before distutils (my setup.py attached). Following is the log, where we see the VS path it is using. BTW, I am trying to reduce my pa

Steve Dower added the comment: You should be able to install "wheel" without setuptools to get the bdist_wheel command. Can you confirm that the build process is actually using that Visual Studio install? If it's going through the regular distutils detection process then it ought to be find

Steve Dower added the comment: Okay, looking at _find_vcvarsall in distutils, I'm guessing that something about how your machines are set up means that the vcredist search is failing. First, could you specify which versions of Visual Studio you have installed, and if possible which one is be

Steve Dower added the comment: I haven't looked into _why_ yet, but the first PYD I grabbed from the GitHub link above has had the CRT statically linked. This is not the default (or it should not be), because when we made it the default this exact issue occurred :) If somehow the default lin
