I have the same problem. On the secondary device the application windows of the primary machine are not shown but only the bottom bar and the wallpaper of the primary pop on.
Primary machine Medion 16 GB with 4 GB ndivida graficcard,
secundary microsoft surface 1 2 GB,
both Windows 10 with newest updates. Also drivers have been updated
spacedesk is listed as exception on the firewall (G-Data). Also not working when disconnecting the firewall and winsecurity.
The connection via browser (HTML) also does only show the bottom bar and the wallpaper.
I run your bat <a href=" removed link " target="true" rel="nofollow">file . The result is shown in a screenshot. There is no spacedesk Graphics Adapter in device manager; with and without connected spacedesk.
