I used old version of Roonserver and it works perfectly. When I update roon remote on iPad, it request me to update Roonserver to 2.0. when I update to 2.0 then there is dialog ‘Your device is not compatible with Roonserver 2.0’ appears on PC screen. I use windows 11 pro PC(Lenovo bare PC) as server and use iPad pro as remote controller. I tried installed Roon on PC but it does not work too.
Are you still having issues with RoonServer starting on your Windows PC? Have you tried to update Windows? You can also try to perform a full RoonServer reinstall by using the below instructions, let us know if this helps.
