"cannot be used..." issue

I have just installed a new motherboard:  MSI MPG Z390 Gaming Edge AC.

Per MSI, Nahimic 3 IS an included feature of this board.    From MSI website,

I have downloaded and installed the latest Realtek/Nahimic driver  MSI 

website states that, after installing the driver, I need to go to Microsoft store

and update Nahimic 3.  I went to the MS Store  and installed the update.

Now, when I start the app, it says:  "Nahimic cannot be used. Your audio driver is not

up to date or your system is not compatible".
