Just asking : Are you aware that allot of people are having installer crashes and leaving LW because they can't install ?
Isn't that a signal to step away from InstallShield and the Windows Installer engine ?

Can I make a suggestion :
Inno Setup 2.0.18 with Martijn laan Extensions .

It's a free one , get it here : http://www.jrsoftware.org/isinfo.php

It's a installer wich isn't dependant on Windows Installer .
And it supports full blown PasCal Scripting , I can even make it play MP3's .

This is also the Installer that Clean LimeWire uses now .
We haven't had a single report of an installer crash or error .

BTW the Clean LimeWire project homepage has moved .
New url : http://limewire.vectorstar.net/

Now how can people discuss what they think of LW if they can't get it to install in the first place ??
You beter get these problems fixed , Afisk ...
