A 32 bit Firebird will work on Windows 64 bit. The only downside that
you can't use all memory available because a 32 bit process is limited
to 2GB, and you might need to account for the fact that it is installed
in Program Files (x86) instead of Program Files (although I seem to
remember that is transparent to 32 bit applications).

BTW: Firebird 2.1.x has always also been available in a Windows 64 version.
