Installing MyBook Live dashboard on MacBookPro

Recently, I changed from a windows laptop to a MacBookPro.
For installation of the MyBooKLive Dashboard on my new Mac, I have downloaded the “My Book Live Setup.app” from the WD support website.
However, when attempting to run the app, an error message informed: “The developer of this app needs to update it to work with this version of macOS. Contact the developer for more information.”
Unfortunately, WD support for this product has ended.
The issue is likely related to the fact that MacOS is now only 64-bit.
My question: Is there 64-bit setup software around for MyBookLive?
Thanks.
