Just a quick suggestion for those who have tried to follow the steps outlined above and have been told that they have the wrong OS when installing instmsiw.exe. I've had similar problems, but managed to solve them by downloading and installing instMsiA.exe (Windows Installer 2.0 I think) from the Microsoft website. I then ran isscript.msi as outlined above and LimeWire installed fine. Hope this helps someone, it worked for me with Windows Me.
