Error "NotFound" while adding RemoteApp in WVD

Question

I logged in both the VM's in my Host Pool and downloaded Notepad++. Then I installed them with Administrator priveleges. After that was done I created a RemoteApp Application Group for my WVD deployment and tried to add Notepad++ as a RemoteApp. The application did appear under "Start Menu" as Notepad++. When clicked Create I was prestented with the error "The resource you are looking for has been removed, had its name changed, or is temporarily unavailable"

Answer 1

It seems that when I add the application based on file path and name it "NotepadPlus" it works but when I select it from the "Start Menu" context it is not able to add the application.
This seems like a glitch in UI (+ sign not allowed?).

Answer 2

@PatrickvanBemmelen Are you using WVD Classic?
If yes, please try the following:

While adding a remoteapp using the command below, mention "Notepad++" (without spaces and with quotes) and it should work.
New-RdsRemoteApp <tenantname> <hostpoolname> <appgroupname> -Name <remoteappname> -AppAlias <appalias>

Other option to try would be using "NotepadPlus" when publishing it.

Let me know the results.
