While configuring a Connector/ODBC DSN, a Could Not Load Translator or Setup Library error occurs

For more information, refer to MS KnowledgeBase Article(Q260558). Also, make sure you have the latest valid ctl3d32.dll in your system directory.

On Windows, the default myodbc5w.dll (Unicode) or myodbc5a.dll (ANSI) is compiled for optimal performance. To debug Connector/ODBC (for example, to enable tracing), instead use myodbc5d.dll. To install this file, copy myodbc5d.dll over the installed myodbc5w.dll or myodbc5a.dll file. Make sure to revert back to the release version of the driver DLL once you are done with the debugging, because the debug version may cause performance issues.
