anti-malware agent on Windows 7?

Why does ZENWorks Antimalware not allow install on Windows versions < 10, when the Bitdefender client it's using supports Windows 7 just fine?

I had to go back and re-install Bitdefender on a few computers after I just got done removing it, but of course the real bitdefender client doesn't interface with the Zen agent...

Is there any way to manually install the bundle on Windows 7?  The bundle itself is apparently hidden in ZENworks so I can't modify the OS version condition to try it out.
