"The installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance"
What to do? I need AirPort Utility 5.6 to be able to run my old airport. I updated airport utility and now it doesn't work. There's another network here so I'm only going to use it for playing music and wi-fi printing. I'm using Lion 10.7.5
How can I install AirPort Utility 5.6?
