Well, you don't give much detail...

But think in terms of the client library being part of the *client 
application*.  So, on the *client machine* you will need the 64-bit client 
available to the application, if it is compiled as 64-bit.

On the server, if you are running a 64-bit application, then you will need the 
64-bit client available *to that application*.  Likewise, if you have a 32-bit 
application (on the server or on a client machine) then you will need to make 
the 32-bit client available *to that application*.

Note that a 64-bit client can interface with either a 32-bit or a 64-bit 
server.  So, too, a 32-bit client can interface with either server type.

On Windows, don't install the client library in the system folder(s) - even 
though the installer gives you that option.  On either the host machine or 
client machines, locate a copy of the client library in the same directory as 
the application executable.  (On POSIX, you can use symbolic links.)

As for "how to tell", it's clear that you found out.  :-(  Your 64-bit 
application has found a copy of a 32-bit client somewhere - showing that you 
can't leave it to good luck.  Note that your standard Windows 64-bit 
installation has copies of both the 64-bit and 32-bit clients.  The 64-bit is 
in the \bin subdir (along with all the 64-bit Fb utility programs) while the 
32-bit is in \wow64.
