The problem is that you are trying to use embedded (ServerType=1), but the fbembed.dll (or fbclient.dll) on your path does not match the runtime bitness (eg 32 bit vs 64 bit).

Are you sure you want to use Firebird embedded? The rest of the configuration string seems to suggest you want to connect to a normal Firebird server, in which case ServerType=0 (or just leaving it off) is better as then you don't have a dependency on a native dll.
