This is Release 4.81 of Popeye.

Downloading Popeye

Popeye executable

In order to use Popeye, you want to download an executable program or the source code to build an executable program yourself.

Windows 64bit: pywin64.exe
Windows 32bit: pywin32.exe
MacOS X: producing an executable for MacOS is always a hassle at best. I wasn't successful this time; if somebody can, I'll be happy to provide it here.

Instead of downloading the source zip archive, you can also clone the git repository or (I assume) use one of the Source Code links.
