I can't install airport extreme software

Hello
I am new to the forum and looking for Help...
I bought airport extreme but can't install the software which come with it.
At the stage where my iMac ask where to install it I have the following message: "Airport utility can't be installed on this disk (mac HD). The version of Mac osx on this volume is not supported"
I have updated my mac to latest software
I am running LION (version 10.7.3)

Many thank to anyone who had same problem and can help

Thanks, Jerzy

Go to Applications, Utilities, Airport Utility should already be there.

Does that mean that I don't need to install the software which came with the product to set up "airport extreme wifi"?
HOpe the answer is yes!

Many thanks for your reply

Yep, there's nothing you need to install. It's already there!
