It appears that as of October 2019 Wine does not work at all on Mac OSX Catalina. This is due to an inability of the OS to run 32-bit applications. In order for this document to work you'll have to get Wine working, and for that you'll have to downgrade your machine to Mojave and you'll have to manually install Wine via the installer instead of using Homebrew. After you've successfully installed Wine you'll have to symlink the tools so they are available in your Terminal:
sudo ln -s /Applications/Wine\ Stable.app/Contents/Resources/wine/bin/wine /usr/local/bin/wine
sudo ln -s /Applications/Wine\ Stable.app/Contents/Resources/wine/bin/winecfg /usr/local/bin/winecfg
sudo ln -s /Applications/Wine\ Stable.app/Contents/Resources/wine/bin/msiexec /usr/local/bin/msiexec
