I can not delete ODBC DSN connection, it i gray out in Tools & Settings -> ODBC Data Sources. How can I delete unwanted DSN?
- DSN was not deleted completely or was created with a error.
- Go to Control Panel - Administrative Tools - ODBC Data Sources (ODBC) - System DSN tab and remove the unwanted DSNs from there.
Also you can delete unwanted DSN using %SystemRoot%\syswow64\odbcad32.exe utility. You will be able to see the DSN created under 64 bit processor.
