Subject AW: [firebird-support] Unable to upgrade database to firebird 3.0
Author Gregor Kobler

Hello Joje


I hade the same problem


You have to choose the client library from a other directory than « c:\program files\firebird\firebird_3_0 »


May you choose «C:\Windows\SysWOW64\FBCLIENT.DLL »


You have to set this in the Host Registration Info under the register connection / client library!



Best Regards

Betreff: [firebird-support] Unable to upgrade database to firebird 3.0



Hello All,

       Recently I upgraded my Firebird from 2.5 to 3.0 and I am using ‘EMS SQL Manager Interbase/Firebird’  to connect and work with database.  Now whenever I connect existing database or register a new database I get following error

 Unsuccessful execution caused by system error that does not preclude successful execution of subsequent statements.

Error loading plugin Engine12.

Module C:\Program Files\Firebird\Firebird_3_0\plugins/Engine12 exists but cannot be loaded.


SQL Code: -901

IB Error Number: 335545004


               I visited EMS website and found there latest version supports upto Firebird 2.5 . Could someone suggest another method to connect to database.


Thanks in advance.


With Regards,

Joje T. George
