Tried all available versions of the drivers (both 32 and 64) and installed onto Win 2008R2 Std 64-Bit servers (virtual) but the Firebird ODBC Setup (from the Control Panel/Admin applet) keeps failing with the error message "Open database 'path:\....\*.fdb' failed". Even moved the DB to the local drive with no success.

The bitness of the driver should be the same as the application and the fbclient. Install the driver on the client machine and make sure the path is valid for remote access, e.g., doggie:D:\databases\mydb.fdb. Substitute the machine name of the host machine for "doggie" here and "D" must be a physical partition on the host, not a remote share.

You need to make sure to use the 32 or 64 bit odbc admin (depends of the fbclient and odbc driver that you use)
32 bit odbc admin -> 32 bit odbc driver -> 32 bit fbclient
64 bit odbc admin -> 64 bit odbc driver -> 64 bit fbclient
