can not load default firebird clients
Lei la documentacion pertinente y encontre que no corre como un servicio a diferencia de los otros OS.
Para que funcione hay que hacer un pequeño ajuste.
Windows 9x or ME
On Windows 9x or ME Firebird server should be running as an application, monitored by the
Guardian. The Guardian's icon should appear in the tray with a green graphic. If the icon is
flashing or showing as a red graphic, it indicates that Guardian is either attempting to start the
server or has failed.
If you used an installation kit that installed but did not automatically start the Guardian and
the Firebird server, you can set it up as follows:
Locate the executable file for the Guardian program (fbguard.exe) and create a shortcut
for it in the Startup area of your machine's Start Menu.
1.
Open the Properties dialog of the shortcut and go to the field where the 2. command line is.
Edit the command line so it reads as follows:
fbguard.exe -a (for Superserver)
fbguard.exe -c (for Classic Server)
3.
4. Save and close the Properties dialog.
Double-click on the shortcut to start the Guardian. The Guardian will proceed to start
fbserver.exe or fb_inet_server.exe.
5.
The Guardian should start up automatically next time you boot your Windows 9x or ME
machine.
Alternatively, you can use a Control Panel applet to control the starting and stopping of the
Firebird server.
