The installer seemed to have the same problem of quitting on me when I clicked outside of its window - but it installed fine after trying again and not clicking anywhere...

If you can't get it to install, I'd try disabling the "Contextual Menu Extension," (using Extensions Manager), restarting the computer, and trying again. Other than that, I don't know what to tell 'ya.

Like I said, the installer was acting up on me, but eventually worked. And the application itself didn't work right until disabling the CM extension.

I'm running Limewire 1.7 on a PowerMac G4, running OS 9.2.1
