In order for Train Sim World to run, it requires third-party system libraries to be installed. These libraries are necessary for the reliable operation of Train Sim World, and it will not run without them. Typically, Steam will install these when you first install Train Sim World but in the unlikely event it fails to do so, here’s how to install them manually.
