Creo que hay algo aqui:

Firebird Client DLLs

The first problem you have is that there are two - arguably three - DLLs that you really have to manage carefully if you are not going to end up with a broken installation. These are, in no particular order:

fbclient.dll:
This is the standard client library used to access Firebird databases via a Firebird Server. The Server is usually on a different system - but doesn't have to be - and the normal resting place for this dll is in the Firebird "bin" folder (e.g. c:\Program Files\Firebird\Firebird_1_5\bin). It may also be found in the Windows System32 folder or in an application installation folder.

fbembed.dll
This is the Firebird embedded server. It does all that fbclient.dll will do for you plus it can access a local Firebird Database without having to go through a separate server. Normal file system access controls then apply for access to local databases, rather than the username/password controls that the normal server uses.. Its normal resting place is the application installation folder. fbembed.dll is often renamed to fbclient.dll or gds32.dll to make it interchangeable with an application designed to use the normal client dll.

gds32.dll
This is the old name for the client dll and is the name still used by InterBase for its client library. Traditionally, this was installed in the Windows System32 folder, but can also be found in the application installation folder. fbclient.dll is often renamed "gds32.dll" when it is used to support Delphi applications that use IBX. It is typically also patched to version 6.3.x so that it is accepted by the Delphi 7 version of IBX. However, this is not necessary for later versions.
