So I'm actually playing this using Wine in OSX. Installation goes well, and on the GOG installer window, at the end I can click Launch and the game runs flawlessly. However, after I exit the game I can't get it to launch again! The LaunchRC.exe file does nothing for some reason! This problem doesn't occur with other games I have also running in Wine, such as Jedi Outcast and Academy.

Does anyone have a solution for this?

Don't use the LaunchRC.exe. It wants a Disc. Use the SWRepublicCommando.exe from the "GameData/System" folder
