Phoenix on Windows: ImportError: DLL load failed

I recently installed Python 3.6 + wxPython/Phoenix on one of my Windows 7 computers. And it works fine.
However, when I came to do exactly the same install on a different machine, it said it had installed okay, but when I try to use it, it fails.
Can anyone advise?

Please check whether you have MSVCP140.DLL.
When you have Visual Studio or the redistributable package
installed, this DLL is sitting in the system32 folder.
You probably can take the files from a .whl file for Python 3.5.
These include msvcp140.dll and vcruntime140.dll.
(Just open the .whl file in e.g. 7-zip.)

Robin has committed the changes. Today's snapshot has the DLL already.
