remoteapp on hyper-v windows 8.1 VM fails to display

anyone know why I can't seem to connect to my VM as a remoteapp session?  It prompts me for my credentials and then nothing happens.  The logs say it authenticated property.  I'm running windows 8.1 pro with hyper-v with a VM of win 8.1 pro also. I'm testing by trying to open notepad.

Does this feature not work if the VM is win 8?

I used this guide (and some others): http://www.simpsoncomputers.co.uk/blog/?p=639

I saved a rdp file and edited the following:

remoteapplicationmode:i:1
remoteapplicationprogram:s:||Notepad
disableremoteappcapscheck:i:1
alternate shell:s:rdpinit.exe
I also set this value in the VM to 1 (and tried 0 too).
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Terminal Server\TSAppAllowList

then i added an applications key and a notepad name and path string...
