Well Norm, in the first place Limewire failed the installation so I don't have to uninstall it. But I did get a fresh download, reinstalled and got the same error...again.

Hmm..ran the isscript.msi as well just to be sure and was prompted by 3 choices: Modify script, Repair script and Remove script. I chose "modify" and reinstalled Limewire but installation still failed.
