The software is distributed as an Esri addin file for use within ArcGIS. After uncompressing the addin (DSASAddin.esriAddIn), you can double-click to launch the Esri ArcGIS Add-In Installation Utility window. Once installation is complete, the DSAS toolbar can be enabled from within ArcMap (compatible with ArcGIS Desktop Standard 10.4 or 10.5) by going to Customize > Extensions and checking the box next to DSAS. The toolbar can then be added via Customize > Toolbars.
The software requires Microsoft .NET Framework 4.5.2 or later and utilizes the ArcGIS .NET Support Feature.
