The RockWare GIS Link 16 program is a toolbar that installs into ArcMap and provides a link between ArcMap and RockWorks16. It is required that both ArcGIS and RockWorks be installed before installing the GIS Link.
If you don't have ArcGIS installed on your computer, you may see this error message when trying to install the RockWare GIS Link 16 program.
