Airport Utility 5.6 would not install on my MacBook Pro with 10.7.5 (Lion): "The installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance." Hello, Apple?
MacBook Pro, Mac OS X (10.7.5)
Use the workaround described in this thread: How do I configure an Airport Express when I get this message in Airport Utility? "This version of AirPort Utility doesn’t support this base station."
Pay attention to the caveat in the final paragraph, restated here for emphasis:
Keep in mind that Apple's decision to abandon support for your original AirPort Express was for reasons known only to them. Remember that you are using obsolete equipment, should some future OS X feature not work for you.
