No, both are 64 bit. But there are two fbclient.dll:
c:\Program Files\Firebird\Firebird_2_5\bin\fbclient.dll,
date Oct 03, 2011, 870912 bytes
c:\Program Files\Firebird\Firebird_2_5\WOW64\fbclient.dll,
date Oct 03, 2011, 548864 bytes
Both were put there by the installation process.

I did this with both dll's, with different results:
Python 3.2.3 (default, Apr 11 2012, 07:12:16) [MSC v.1500 64 bit (AMD64)] on win
32

Translation of the Windows error: '%1 is not a valid win32-application'.
Looks like something is wrong with the dll in WOW64, but what, and what should
I do? Simply remove it (but perhaps it is needed somewhere)? Uninstall and
reinstall Firebird?
Thank you for your help,
