As I only run Firebird as a service, I run through a list of all
installed services and take the binary path of all services whose
service name (not DisplayName!) begins with "FirebirdServer". Seems to
work OK for me, updates my UDF for all installed Firebirds - regardless
of whether they have a key in registry or not.
