RivEX provides several admin tools, the most important one being the create a license code.  You will not be able to use RivEX on your data until you have purchased RivEX and installed the license file.  Using the create a license code tool is discussed here.

Other admin tools allow you amend the synonym list used in the snapping tool, export the topological data into simple plain text files that you could use in other applications, maintain the settings file and remove redundant outputs.
