HI, Not sure if this is the right place to ask, but I am trying to build pywin32-224 from source for Python 3.7.4. I think this might be the right list as this seems to be a generic problem I am having, but I want to focus on one particular module. First, I know I could get this via 'pip install', but I want to build from source to see what it takes in terms of the Windows SDK and Visual Studio versions for some other work I am doing. I am using Python 3.7.4, and I have Visual Studio 2017 15.9 (released July of this year). I see this when running 'python setup.y build': <bunch of stuff elided> error: Microsoft Visual C++ 14.1 is required. Get it with "Microsoft Visual C++ Build Tools": https://visualstudio.microsoft.com/downloads/ I have tried various compilers from that link (VS 2015, VS 2017, and even VS 2019), but no joy. I also have the Windows SDK 8.1 and 10 installed (pywin32 wants the 8.1 SDK) Does anyone have any ideas as to what I am doing wrong, or if there is some weird underlying issue with setuptools and/or distutils? Thanks, Tom
