Was seeing the following error when attempting to view the ODBC configuration for eDNA on a particular server that had the User Client and Business Connector installed.
The setup routines for the InStep eDNA Business Connector ODBC driver could not be loaded due to system error code 126: The specified module could not be found (c:\program files (x86)\eDNA\EBC\InStepEBC_64.dll).
Installing the Microsoft Visual C++ 2010 Redistributable Package per this post fixed the problem:
