Any book from InstallShield will target, market and promote the use of InstallShield's packaging tools. I've found the range of books from InstallShield to only contain approximately 30% of useful material for those not contemplating using InstallShield's development tools.The only book which had a generic focus on Windows Installer has been Mike Gunderloy's book. I say "had" because it is no longer in print.If you are not planning to commit your investment in Installshield's products, I would not recommend any book from InstallShield Corporation given cost and the overall content which will be applicable to your MSI development efforts.
