Hi, I just downloaded version 2.20 of DBExpress driver for Interbase. I am using Delphi 7 and also the embedded version 1.5.3 of Firebird. I am trying to connect to an Interbase 2007 database and an error message appears: "unsupported on-disk structure for file psicoplus.gdb; found 12.10, support 21837740.21833620".

In the TSQLConnection I chose the "Interbase (Core Lab)" connection name. I also renamed the file "fbembed.dll" to "gds32.dll" and placed it in the same directory where the executable is.

Has anyone experienced any problems connecting to an Interbase embedded database?

Using the Firebird embedded client you can connect to Firebird embedded database. But it does not support Interbase 2007 embedded database.

Ok. I created a Firebird database, but now the message that appears is "unnavailable database"... When I start Firebird 2.0 Server, then it connects to it.

I can't make it work... I need to create a standalone application with Interbase or Firebird embedded, but it's not working...

Please specify whether you have specified host name in the DataBase connection parameter. For embedded server you should specify only file name with its path.

I didn't specify the host name, only the file path... Is there any demo project showing how to make this work?

Probably, your application uses another gds32.dll. Please check that there is no gds32.dll file in Windows\System32 folder. You also can try to uninstall all Firebird/InterBase clients and servers from your computer except the client with embedded server.
