Thanks so much that env var was all I needed :) The way it was working was that you'd run the main exe, it would call steam and close the main exe. Steam would then launch the front end launcher and then clicking launch on that would run whatever was defined in install.vdf. Now I just set the env var in the hook and run the exe and everything works as expected.

I'm working on getting full mod support for Call of Cthulhu: Dark Corners of the Earth. I've got the GOG and retail version working (no DRM) using a hook loader to override all the file opens. I want to get the Steam version working but things are a little more complicated. For Steam running the main exe ends up going through Steam and running C:\Steam\steamapps\common\Call of Cthulhu\install.vdf. Install.vdf defines the exe to run as "Executable" "%INSTALLDIR%\\Engine\\CocMainWin32.exe" which if I change it to "Executable" "%INSTALLDIR%\\mods\\Engine\\DCoTEHook.exe" which is my hook everything works as expected just like the GOG version. So my two questions are: Does anyone know of a better way to do this that doesn't require changing the install.vdf file? and If that is the only way then what is the best practise way with Vortex to make that change and have it be able to be reversed when the mod is removed?
