Eryk Sun added the comment: "Tools/msi/README.txt" still references "%SystemRoot%\System32" and "%SystemRoot%\SysWOW64" as the location of "python3[x].dll" for all-users installs. The containing paragraph can be removed. Move the lines for ".\python3x.dll" and ".\python3.dll" unconditionally into the installation directory listing. Maybe also add ".\vcruntime140[_1].dll" to the listing. ---------- versions: +Python 3.10, Python 3.8, Python 3.9 -Python 3.5, Python 3.6, Python 3.7 _______________________________________ Python tracker https://bugs.python.org/issue29844 _______________________________________
