Unfortunately, you are right, the software is not available for iMac's operating system. I've downloaded both archives and extracted their content only to find out that an EXE and a MSI file is bundled within which confirms Windows compatibility.
You can install the application with something else called Wine Bottler that allows you to run Windows apps on a Mac without installing the proper operating system.
Note: It's OK if it works, but if you need drivers, then another problem will pop up since the software doesn't install drivers and you'll have to fully install Windows through Bootcamp or Parallels Desktop.
