I just updated my airport uitility (6.2) and when opened it said it didn't support my AirPort Express. I tried replacing with previous version from backup, but Finder won't allow modifications. Any help appreciated, since I'm stranded now.
MacBook Pro, OS X Mountain Lion (10.8.2)
Go back in your Time Machine backups to see if you can locate AirPort Utility 5.6.
If yes, restore AirPort Utility 5.6 to the desktop on your Mac.
Make sure that it is named AirPort Utility 5.6....not just AirPort Utility
Then manually drag the application into the Utilities folder.
This works for me, but if this does not work for you, there are other workarounds....or, you can do what Apple wants you to do and buy a new AirPort Express.

If you have an 802.11b/g Express, AirPort Utility 6.2 will not be able to do anything with it.
You need AirPort Utility 5.6 to configure an older Express. The problem with that version is that Mountain Lion will refuse to let you install it.
This dilemma is easily solved. You simply need to extract the app from the installer package using a package extractor like Pacifist or unpkg. Pacifist is shareware, unpkg is free.
Download Pacifist here: http://www.charlessoft.com/
Download unpkg here: http://www.timdoug.com/unpkg/
Download AirPort Utility 5.6 here: http://support.apple.com/kb/DL1482
When the AirPort Utility .dmg file finishes downloading, open it to expand and reveal the AirPortUtility56.pkg package installer file.
Directions for Pacifist (I do not have screenshots for unpkg but the idea is similar):
Open Pacifist and from its File menu, navigate to the package and open it.
Click the "reveal triangles" until you see AirPort Utility 5.6.app:
Select it and then click Install from Pacifist's toolbar. It will then be installed in your Utilities folder, and you can quit Pacifist.
Mountain Lion will not allow you to delete its existing version of AirPort Utility. Just ignore it. It and the older version (which will bear the unique name "AirPort Utility 5.6") can peacefully coexist.
If you happen to have an archived copy of the AU 5.6 app somewhere, such as a Time Machine backup or equivalent, you can simply restore it or drag the app to your Mountain Lion system's Utilities folder instead of resorting to the above procedure. It will run without complaint. It is only the package installer that is the problem.
If you have an older computer with a version of AirPort Utility earlier than 6.0, you can administer it that way as well.
Thanks Bob, John for quick responses. This solved it.
Now why doesn't Apple warn you? (No need to answer that)
