I posted to the thread that you mentioned. It looks like most of the people posting were probably using the 1.6d installer from the dates of their posts. We have definitely had problems with those InstallAnywhere 3.5 installers on different Mac configurations, but we were hoping that the IA 4.01 version (the version we're using in LimeWire 1.7) would work a little bit better.

The tricky part here is that we're really doing the simplest install possible, so if the installer fails, there's really not much we can do about it except wait until InstallAnywhere releases an updated version (which they will be doing fairly shortly).

Hopefully, however, people will not have problems with the new installer.
