Microsoft, in an attempt to force people to stop playing older games 
and purchase newer offerings, has eliminated several DLL files in Windows 11.

Windows 11 users need to install these four dgVoodoo (ver 2.86.5) files into
the folder "Train Simulator" (where the MSTS executable file is located):
D3D8.dll
D3D9.dll
D3DImm.dll
DDraw.dll
