InstallShield 2009 Upgrade Caveats
There are many great new features, improvements and bug fixes in InstallShield 2009, as detailed in the release notes. But if you consider upgrading to the new version you also should be aware of some changes that might be a problem for your projects. I'd like to highlight the following issues, but please also review knowledge base article Q200151.
Stand Alone Build engine (SAB) is only available for owners of the Premier edition. It was removed from the Professional edition with the release of InstallShield 12, but users upgrading from InstallShield Professional 10.x or 11.x which included the SAB could get the current version free of charge. With InstallShield 2009 this is no longer possible. If you need the Stand Alone Build you must buy Premier.
FLEXnet Connect (formerly InstallShield Update Service) support is only available in MSI projects. If you are using pure InstallScript projects you can no longer add this update notification tool to your setup. For InstallScript MSI it is still available but some script functions related to FLEXnet Connect have been removed. For Basic MSI projects FLEXnet Connect continues to be supported as usual. (FLEXnet Connect is an add-on to InstallShield that is charged separately.)
