I tried to connect a Firebird Database in QGIS 2.2 and 2.4 via ODBC to a database and get following error message:
Unable to initialize ODBC connection to DSN for SYSDBA/masterkey@Akdees [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application
Funny, that it does work with QGIS 1.8! but fails with QGIS 2.2 and 2.4. Does anyone have an idea as to what the reason is and how to make it work again?
