Notice that "vcruntime140.dll" appears twice on this list, once near the top and once near the bottom.

If we try to unpack this using the powershell Expand-Archive command, it fails with:

Failed to create file 'D:\a\1\s\python-dir\vcruntime140.dll' while expanding the archive file 
'D:\a\1\s\python.zip' contents as the file 'D:\a\1\s\python-dir\vcruntime140.dll' already exists. Use the -Force 
parameter if you want to overwrite the existing directory 'D:\a\1\s\python-dir\vcruntime140.dll' contents when 
expanding the archive file.

Probably it would be better to only include one copy of vcruntime140.dll :-)
