Installers

Installers are currently available for Windows®, Linux®, and macOS® JDK and JRE packages. Installation stepsare covered in the following sections:

Windows MSI installer packages

AdoptOpenJDK Windows installer packages are available as standard .msi files, which can be run with an interactive user interface or run silentlyfrom the command line. The installer is designed for use on a per-machine basis, not per-user basis, so you can have only one installation of the MSIon a machine for all users.

Note: Windows installer packages are supported only on Windows x64 systems.

GUI installation

Instructions for running an interactive installation using the Windows MSI installer.

1. Download the .msi file. Open it to launch the installation program.

2. Read and accept the license if you are happy with the terms.

3. On the Custom Setup screen you can choose the features that you want to install and optionally change the default installationdirectory. By default, AdoptOpenJDK installs to c:Program FilesAdoptOpenJDK<package> with the following features, which you can deselect, if necessary:

Add the installation to the PATH environment variable
Associate .jar files with Java applications

Additional features can be selected by clicking on the directory tree where you see a check mark (x). These features include:

Updating the JAVA_HOME environment variable
Installing IcedTea-Web (AdoptOpenJDK 8 only)
Associate .jnlp files with the IcedTea-Web application (AdoptOpenJDK 8 only)

4. When you have chosen the features that you want to install, click Next.

5. Click Install to begin the installation.

6. When the installation is finished, click Finish to close the program.

Command-line installation

A silent installation allows you to install the Windows package with pre-selected features without user interaction, which can be useful for widescaledeployment. Follow these steps:

1. Download the .msi file.

2. Choose the features that you want to install, which are shown in the following table:

Feature	Description
`FeatureMain`	Core AdoptOpenJDK installation (DEFAULT)
`FeatureEnvironment`	Update the PATH environment variable (DEFAULT)
`FeatureJarFileRunWith`	Associate `.jar` files with Java applications (DEFAULT)
`FeatureJavaHome`	Update the JAVA_HOME environment variable
`FeatureIcedTeaWeb`	Install IcedTea-Web
`FeatureJNLPFileRunWith`	Associate `.jnlp` files with IcedTea-web
`FeatureOracleJavaSoft`	Updates registry keys HKLMSOFTWAREJavaSoft

Note: FeatureOracleJavaSoft can be used to prevent Oracle Java launching from PATH when AdoptOpenJDK is uninstalled. Reinstall Oracle Java if you needto restore the Oracle registry keys.

Optional parameters can be used that group some of the features together:

Parameter	Features
INSTALLLEVEL=1	FeatureMain,FeatureEnvironment,FeatureJarFileRunWith
INSTALLLEVEL=2	FeatureMain,FeatureEnvironment,FeatureJarFileRunWith,FeatureJavaHome,FeatureIcedTeaWeb
INSTALLLEVEL=3	FeatureMain,FeatureEnvironment,FeatureJarFileRunWith,FeatureJavaHome,FeatureIcedTeaWeb,FeatureJNLPFileRunWith

3. Run the command on the target workstation.

The following example silently installs AdoptOpenJDK, updates the PATH, associates .jar files with Java applications and defines JAVA_HOME:

The following example silently installs all the features for INSTALLLEVEL=1:

If you want to launch an interactive installation in another language you can use the Windows installer TRANSFORMS option to setyour language choice. For example, to set the UI language to German, use code 1031, which must be preceded by a :.
