The format of SimSig's simulations has changed. Instead of each simulation being a stand-alone application (.exe), simulation files now consist purely of data, and are launched via the SimSig Loader. As such, simulations no longer have a shortcut on the desktop or in the Start menu. Instead, there is a shortcut to the SimSig Loader, from which you can select a simulation to run.
If you don't have a shortcut to the Loader, you haven't installed the System Files , which include the Loader, License Manager and a few other files needed to run the simulation.
Further information can be found in the Installation Guide and the Starting a simulation page.
Historical note: Some simulations haven't been updated to use the SimSig loader. These are listed on the pages linked to above, and are launched the traditional way via a shortcut on the desktop/start menu.
