You must create a new registry key named InstallLocation at [HKEY_LOCAL_MACHINE\Software\Wow6432Node\Madia\Echelon 1.5]. In the value specify the virtual Wine path to the game root folder.
The startup script can be greatly simplified if you use Steam as a laucher.
@echo off
start /wait Options.exe
start /wait Game.exe
Windowed mode seems to be broken.
