Publish .exe file as a RemoteApp in Server 2019. App is not installed on session host

Question

Hi all,

I'm trying to publish an .exe file as a RemoteApp in Server 2019. The .exe is located on a different server (app server where we have all of our applications )and when I point to it using a UNC path I get the following error message:

You must specify a file from the RD Session Host server, Remote.####.Local by using the UNC path; for example, \Remote.####.local\c$\path\filename.exe.
