Unable to load fbclient.dll

I have written an application using D7 and dbExpress components. I'm using dbexpint.dll as my connection component and it needs the fbclient.dll to talk to Firebird. The application was written in D7 on XP and Firebird 2.5 (all 32bit).

The server I need to run it on is Win2k8 Server, 64bit. Is it possible that my dbexpint.dll cannot load/use the 64bit Firebird fbclient.dll ?

Thinking it might be a permission issue, I copied the fbclient.dll from the default Firebird folder to the same folder as the application server that I wrote. Still same error message.

I uninstalled Firebird and re-installed it, and this time I checked the box for the installer to put a copy of fbclient.dll in the system folder, so that it is accessible to all programs. I can now access all my 64bit Firebird databases. ie: It was a permissions issue not a dbExpress issue.
