I should have included this info ...
I am currently running MacOS X 10.2.3, but I have gotten that same installer message for close to a year, going back to v10.1.x
I don't know what version of LimeWire I was able to using during that year, since they make it all but impossible to tell. I wish I hadn't pitched it in hopes that it would make it possible to install the current version!
