After reading and re-reading this book for most of a year, I have yet to glean any useful information from it. The author has a very wordy writing style, which tends to obscure an already complex subject. He spends many pages essentially repeating what is in the InstallShield online help, giving lots of detail on what to do, but nothing on when or why to do it.
