When the Windows GUI (fwpolicy) is started in Firewall-1 3.0 and the login process is initiated, the error message window pops up displaying this message.
The Firewall-1 GUI packages SUNWfwgui and SUNWfweui were installed in the incorrect order. First, remove the packages using pkgrm(1M). Next, install the SUNWfwgui and, then, the SUNWfweui in that order to resolve the error message.
