install4j is a powerful multi-platform Java installer builder that generates native installers and application launchers for Java applications. install4j excels in its ease of use, its extensive platform support and its powerful screen and action system.

EXCEPTIONAL EASE OF USE
Some installer builders require that you first become an expert in building installers. Not so with install4j, where all configuration steps are intuitive and self-explanatory. The install4j IDE guides you naturally through the process of gathering required information. Building an installer that works is a matter of minutes. Nonetheless, you have a powerful arsenal of functionality at your disposal when you need it.

BEAUTIFUL INSTALLERS
The installer is the first thing your users see of your application. A smooth installation experience is an important step in creating happy users and a successful product. A substandard installer, however, can ruin the initial impression that is so important for the image of a product. With install4j, your installers will look beautiful and feel natural to users on all platforms.

RICH SCREEN & ACTION SYSTEM
With install4j, you can configure the screen flow for the installer and uninstaller in any way you like. install4j provides screens and actions for a wide variety of use cases and allows you to create your own actions directly in the install4j IDE. Actions can be attached to each screen, making install4j a visual programming system far more powerful than traditional installer builders.

AUTO-UPDATERS AND CUSTOM APPLICATIONS
install4j offers several templates for updaters that enable you to create an auto-update solution for your application with just a few clicks. Auto-updaters are fully customizable, so they can support your special requirements for a large number of scenarios. More generally, install4j supports the creation of custom installer applications that are packaged with your application.

SIMPLE CREATION OF CUSTOM SCREENS
Querying information from the user that's specific to your application does not have to be hard. Besides programming your own custom screens, install4j includes a unique concept of form screens that look good and are easy to configure. With its powerful variable system, install4j enables you to use the entered information in other screens and actions. Creating a user interface cannot get any easier than this.
