Using a Configuration File

jdk INSTALLCFG=configuration_file_path

• jdk is the installer base file name, for example, jdk-11_windows-x64_bin.exe.

• configuration_file_path is the path to the configuration file.

Configuration File Options

The Table lists the installer configuration file options that apply for Windows operating system.
