Install4j

Install4j is a powerful multi-platform Java installer builder that generates native installers and application launchers for Java applications.

New features:

• Windows launchers now support OpenJ9 JVMs
• Added the compiler variables sys.mediaFileSeparator and sys.mediaPathlistSeparator containing separators specific to the target platform of the current media file
• "Update alert" form component: Added an "Initially selected choice" property

API changes:

• Added Context#gotoScreen(Screen, boolean, boolean) for navigating to a screen while optionally checking the condition of the target screen and executing actions, similar to Context#goForward(int, boolean, boolean)
• Added InstallerActionEvent#getActionId() returning the ID of the action that triggered the event
• Added Context#getId(Action) and Context#getId(Screen)
• Added Context#isGui()
• JVMSelector#setPreferredJVM now also works in custom installer applications
• JVMSelector#getJVMLocations could not handle JRE locations ending with "jre" on macOS, so passing System.getProperty("java.home") as an additional location did not work
• JVMSelector#getJVMLocations now also considers the JRE set with the environment variable INSTALL4J_JAVA_HOME

Bugs fixed:

• Security: Prevent DLL hijacking for Windows installers with Java 11+ on Windows 8.1 and earlier
• Regression in 7.0.9: When using merged projects, overriding a compiler variable in the main project with another compiler variable threw an exception
• Regression in 7.0.9: Compiler variables in styles could be replaced with their values if the preview functionality was used for a screen and the style was subsequently edited
• "Download file" action: Installer variables were not replaced in the "Optional md5sums URL" property
• "Windows user selector" form component: Show a more specific error message when a Windows user cannot be created because the user name is invalid
• "File associations selector" form component: The displayed file associations depend on which launchers are contained in the the selected installation components. Going back to the installation components screen and changing the installation components would not update the list of displayed file associations.
• File and directory chooser form components: In console mode, if the initial value was set to an installer variable with an empty value, the suggested value was not empty but the working directory
• Form screens: If the "Screen can be reached" property was set to "Only with Back button", the screen was not shown when the user used the back button on the next screen
• Windows: Invoking the uninstaller directly from a mapped drive did not work correctly
• Windows: Fixed problems with Java 11+ and DLL loading when other JREs are in the PATH environment variable
• Windows: Java 11+ 32-bit installers did not work for users with different long and short path of their home directory
• Windows: Installers now try to write temporary files to %ProgramData%install4jtemp if the user-specific temporary directory is not usable
• Linux/Unix: Made the workaround for running installers on systems where no fonts are installed more reliable and also cover custom installer applications as well as the the uninstaller
