By default 32 bit applications are not allowed to read the 64 bit
registry. They only see the area of the registry for 32 bit programs (The
Wow6432Node). As the Firebird 64 bit element is written in the 64 bit
registry, it is not visible. You can access 64 bit nodes if explicitly
requested, but I am not 100% sure if and how that works. See also

and

Why does your application need to know the location of the Firebird
server? Also if you want to use ODBC from a 32 bit application, then you
need to use the 32 bit ODBC driver!

BTW: The correct registry key for Firebird is with a lowercase b (at least
for 2.5).
