Some modern digital audio workstations (like Studio One 3 and later, Steinberg Cubase Pro X, Steinberg Dorico, etc.) require the Windows 7 Platform update even if the WINE host is set to Windows 10 x64.
According to my tests with these applications running on Windows 7 Embedded: Even if the platform update is installed, they don't run unless the Windows Aero is enabled (i.e. the DWM is running).
Hence, the current issue is not solvable until WINE introduces full support of DWM.
It might be worth trying to return TRUE for Aero support and see how the app behaves: https://source.winehq.org/git/wine.git/blob/HEAD:/dlls/dwmapi/dwmapi_main.c#...
