My Cloud Mirror Gen 2 Anti-Virus Essentials

Can you install Anti-Virus Essentials on a MCM Gen 2? Just updated the Firmware and still not showing in list even after I attempted to install it manually via a download from the My Cloud Mirror Gen 2 site itself.
Have looked at https://support-en.wd.com/app/answers/detail/a_id/3021/kw/virus%20scan
See https://support-en.wd.com/app/products/product-detail/p/137#WD_downloads that shows Anti-Virus Essentials under the Third Party Apps GPL Codes that are compatible with the MCMGen2. And yet it is not installing…

Any idea why it does not show or won’t install?

The Anti-Virus Essentials is not available for installation in WD My Cloud Mirror Gen 2.
