Firebird/InterBase(r) driver 2.00.05.156

Firebird ODBC Driver is distributed with CompareData and the driver is used by the app to connect to its embedded repository.

SQL Error, SQLState: 08004, Return Code: -1
[ODBC Firebird Driver]Unavailable Database

SQL Error. Native Code: -902, SQLState: 08004, Return Code: -1
[ODBC Firebird Driver]File Database is not found

Only one instance of the application can connect to the embedded Firebird database at the same time.

Verify that no other application is connected to the embedded repository database. You can use Windows Task Manager to look for cmpdata.exe to ensure that only one instance of the application is connected to the embedded repository.

This error may also be due to another application using the embedded Firebird client (fbclient.dll) or if the database file does not exist.
