That came from Trainsimulations web site, correct? While it comes with a nice package installer (something goku never provided), which is easy for newbies to get up and running and start creating consists, that version is quite old with respect to route editing needs and doesn't even have the shape viewer replacement component, either.
0.7012 is the most current.
I wish TS would update that installer, and provide a third icon for shape viewer, but then again their business goal is to sell their routes, not enable others by handing out newer more competent versions of TSRE.
In the meantime, I started with the TS installer, but then upgraded the TSRE folder "guts" to more current versions which required editing the two batch files to reflect the newer version number and adding a third desktop icon for shape viewer.
