Topic "Unable to find Microsoft Remote Desktop" a message from qt02537

When I try to open a new RDP session, I get the message:
&quotUnable to find Microsoft Remote Desktop. Get it from the App&quot (see attached screenshot)

I've got the Mac version of Microsoft Remote Desktop installed, but I still get this message.
Researching this forum, it sounds like it should use the &quotembedded version&quot.

Please advise.
