I get error "[unixODBC][][Easysoft][InterBase]unavailable database" when connecting through the ODBC-ODBC Bridge to InterBase. What can I do?

There are two solutions to this problem. Firstly, you can make sure that you pass in localhost: at the beginning of the database path in your InterBase data source. Alternatively, you can enable Services > Easysoft ODBC-ODBC Bridge Server > Properties > Log On > Allow service to interact with desktop. (Be sure to restart the ODBC-ODBC Bridge service afterwards.)
