The installation of an Emergency 4 submod is not a "next, next, finish" affair. It is a ritual. You must navigate to the install directory, usually buried deep in the C: drive, past Program Files, past x86. You are handling the guts of the software. You must backup the original Specs folder, for if you fail, the game will crash on startup, a black screen of judgment.
This usually happens if the mod was installed in a sub-folder rather than the main "Mods" directory. emergency 4 wegberg 7 submod download
