I made some changes to my installer but QuickBuild does not seem to include the changes. How do I update it?
You can use the QuickBuild button to avoid rebuilding an installer from scratch if you are just making changes to installer-specific settings, such as: license and readme file, default installation path, logo image, installation required by root, product name and version, and so on. Those settings will be updated without having to pack every product file again. You will need to follow the normal build process if you make changes to the product files themselves (the ones you added in the Files screen.) The QuickBuild feature is intended to make interactive development of installers easier, especially of large installers containing many files. When creating installers for release to others, you should use always use the regular build function.
