    I just installed Python 3.9.0b5 using the provided beta installer python-3.9.0b5-amd64 on a Windows7, 64bit machine.

    I did the installation without the Py Launcher update, into the folder "c:\python39"

    The installer finished without problem.

    Running "cmd.exe", navigating to "c:\python39" and then running python.exe results in an error message popup which tells me in
    German system language that the "api-ms-win-core-path-l1-1-0.dll" is missing on the computer. I googled for it and it seems that this dll is not a part of Windows 7.

    Message:

    ---------------------------
    python.exe - Systemfehler
    ---------------------------
    Das Programm kann nicht gestartet werden, da api-ms-win-core-path-l1-1-0.dll auf dem Computer fehlt. Installieren Sie das Programm erneut, um das Problem zu beheben.
    ---------------------------
    OK

    Changed "component" from "resource" to "crash" because it seems to fit better.

    that the "api-ms-win-core-path-l1-1-0.dll" is missing on the computer.
    I googled for it and it seems that this dll is not a part of Windows 7.

    Microsoft ended extended support for Windows 7 back in January of this year, so Python 3.9 does not support Windows 7, in accordance with PEP-11 1. I'd expect the installer to fail on unsupported versions of Windows.

    I thought we already made it fail? (Checks) No we did not. Guess I misremembered that.

    I'll fix this tomorrow. We need it, or else we'll be inundated with these reports for the entire life of 3.9.

    Leaving this open until we can validate on the next release. I don't have convenient access to old versions of Windows anymore (and don't have time to deal with inconvenient access this week).

    "Leaving this open until we can validate on the next release".

    You should be able to do it now, Steve.

    I forked the official cpython and made some hacks for supporting win7+. See https://github.com/liudonghua123/windows-python-installer for more details.
