So are you saying it depends on the client application, rather than the client OS?

But Delphi apps (always 32bit) run quite happily on my 64bit W7 machine, where both FB server and FB client are 64bit.

However, we have had trouble on a client site, where a 64bit terminal server acts as a client to a 32bit FB server. 64bit version of fbclient does not seem to work, while 32bit fbclient does.
