The 11.0 release of ArcGIS Roads and Highways includes minor enhancements to the software and the documentation.
The stand-alone Location Referencing installer is no longer necessary in 10.9 or later releases. However, the software must be authorized using your Location Referencing license key on each machine on which it is installed.
You can download the ArcGIS Event Editor from My Esri.
