If you are looking for zpy.dll you are probably in ZoneAlarm hell right now. For some reason you decided to try uninstalling, then reinstalling v6.5 of the firewall, maybe because your Eudora email client was having kittens or your anti-virus software wouldn't update ... It doesn't matter because you're there now, trying to get the damn thing to reinstall but faced with a dumb message that zpy.dll is missing and perhaps you should reinstall the application - like you hadn't thought of that already.
