Installer - Available Actions



 Install files
     
Install all files in the distribution tree that are contained in the selected installation components.
Applies to: Installation
Properties:
  • Insufficient disk space warning
    Show a warning message if there is not sufficent disk space for the installation on the selected target drive.
  • Delay if necessary
    If selected and a destination file cannot be replaced, the operation will be scheduled for the next reboot. The variable sys.rebootRequired will be set to Boolean.TRUE in this case.
  • Directory resolver
    Expression or script that resolves the actual installation directory separately for each installed file. Return null, if you would like to choose the standard installation directory for a file.
  • File filter
    Expression or script that is invoked for each file to decide whether to install the file or not.
  • Install runtime
    Create the installation directory and install the install4j runtime. If your installer just modifies some folders and does not need launchers, an uninstaller or custom installer applications, you can deselect this option and use other installation roots in the distribution tree to install files.
  • Show file names
    If set, the names of the files that are installed will be shown during the installation.
  • Installation size calculator
    Expression or script that calculates a custom installation size in bytes. The default size in bytes is passed as a parameter.
  • Trigger reboot if required
    If selected and an operation is delayed until reboot, the user will be asked for a reboot automatically at the end of installation.
  • Validate application id
    Check if another application is installed in the selected directory or if the application is not the correct target for an add-on installer. If you have an "installation location" screen, you don't have to select this option.
