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:

What

1. Download the .msi file.

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

FeatureDescription
FeatureMainCore AdoptOpenJDK installation (DEFAULT)
FeatureEnvironmentUpdate the PATH environment variable (DEFAULT)
FeatureJarFileRunWithAssociate .jar files with Java applications (DEFAULT)
FeatureJavaHomeUpdate the JAVA_HOME environment variable
FeatureIcedTeaWebInstall IcedTea-Web
FeatureJNLPFileRunWithAssociate .jnlp files with IcedTea-web
FeatureOracleJavaSoftUpdates 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:

ParameterFeatures
INSTALLLEVEL=1FeatureMain,FeatureEnvironment,FeatureJarFileRunWith
INSTALLLEVEL=2FeatureMain,FeatureEnvironment,FeatureJarFileRunWith,FeatureJavaHome,FeatureIcedTeaWeb
INSTALLLEVEL=3FeatureMain,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:

Note: You must use INSTALLDIR with FeatureMain.

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 :.

For a list of supported codes, see the Language list.

Reinstalling or upgrading

To reinstall AdoptOpenJDK in silent mode with default features, run the following command:

If you want to upgrade AdoptOpenJDK in silent mode, run the following command:

What

REINSTALLMODE options: (from Control Events)

  • a: Force all files to be installed regardless of checksum or version
  • m: Rewrite all required registry entries from the Registry Table that go to the HKEY_LOCAL_MACHINE
  • o: Reinstall if the file is missing or is an older version
  • u: Rewrite all required registry entries from the Registry Table that go to the HKEY_CURRENT_USER or HKEY_USERS
  • s: Reinstall all shortcuts and re-cache all icons overwriting any existing shortcuts or icons

Note: REINSTALL=ALL automatically sets REINSTALLMODE=omus

Upgrade limitation:

Upgrading .msi files works only for the first 3 digits of the build number due to an MSI limitation:

  • Upgrading 8.0.2.1 to 8.0.3.1 works.
  • Upgrading 8.0.2.1 to 8.0.2.2 does not work. Uninstall the previous .msi and install the new one.
  • Upgrading 8.0.2.1 to 8.1.2.1 works.
  • Upgrading 8.0.2.1 to 11.0.2.1 does not work. AdoptOpenJDK does not provide upgrades for major versions. Either keep both installations or uninstall the older one.

Introduction

Most modern Unix-like operating systems offer a centralized mechanism for finding and installing software. Software is usually distributed in the form of packages, kept in repositories. Working with packages is known as package management. Packages provide the basic components of an operating system, along with shared libraries, applications, services, and documentation.

A package management system does much more than one-time installation of software. It also provides tools for upgrading already-installed packages. Package repositories help to ensure that code has been vetted for use on your system, and that the installed versions of software have been approved by developers and package maintainers.

When configuring servers or development environments, it’s often necessary look beyond official repositories. Packages in the stable release of a distribution may be out of date, especially where new or rapidly-changing software is concerned. Nevertheless, package management is a vital skill for system administrators and developers, and the wealth of packaged software for major distributions is a tremendous resource.

This guide is intended as a quick reference for the fundamentals of finding, installing, and upgrading packages on a variety of distributions, and should help you translate that knowledge between systems.

Package Management Systems: A Brief Overview

Most package systems are built around collections of package files. A package file is usually an archive which contains compiled binaries and other resources making up the software, along with installation scripts. Packages also contain valuable metadata, including their dependencies, a list of other packages required to install and run them.

While their functionality and benefits are broadly similar, packaging formats and tools vary by platform:

Operating SystemFormatTool(s)
Debian.debapt, apt-cache, apt-get, dpkg
Ubuntu.debapt, apt-cache, apt-get, dpkg
CentOS.rpmyum
Fedora.rpmdnf
FreeBSDPorts, .txzmake, pkg

In Debian and systems based on it, like Ubuntu, Linux Mint, and Raspbian, the package format is the .deb file. APT, the Advanced Packaging Tool, provides commands used for most common operations: Searching repositories, installing collections of packages and their dependencies, and managing upgrades. APT commands operate as a front-end to the lower-level dpkg utility, which handles the installation of individual .deb files on the local system, and is sometimes invoked directly.

Recent releases of most Debian-derived distributions include the apt command, which offers a concise and unified interface to common operations that have traditionally been handled by the more-specific apt-get and apt-cache. Its use is optional, but may simplify some tasks.

CentOS, Fedora, and other members of the Red Hat family use RPM files. In CentOS, yum is used to interact with both individual package files and repositories.

In recent versions of Fedora, yum has been supplanted by dnf, a modernized fork which retains most of yum’s interface.

FreeBSD’s binary package system is administered with the pkg command. FreeBSD also offers the Ports Collection, a local directory structure and tools which allow the user to fetch, compile, and install packages directly from source using Makefiles. It’s usually much more convenient to use pkg, but occasionally a pre-compiled package is unavailable, or you may need to change compile-time options.

Update Package Lists

Most systems keep a local database of the packages available from remote repositories. It’s best to update this database before installing or upgrading packages. As a partial exception to this pattern, yum and dnf will check for updates before performing some operations, but you can ask them at any time whether updates are available.

SystemCommand
Debian / Ubuntusudo apt-get update
sudo apt update
CentOSyum check-update
Fedoradnf check-update
FreeBSD Packagessudo pkg update
FreeBSD Portssudo portsnap fetch update

Upgrade Installed Packages

Making sure that all of the installed software on a machine stays up to date would be an enormous undertaking without a package system. You would have to track upstream changes and security alerts for hundreds of different packages. While a package manager doesn’t solve every problem you’ll encounter when upgrading software, it does enable you to maintain most system components with a few commands.

On FreeBSD, upgrading installed ports can introduce breaking changes or require manual configuration steps. It’s best to read /usr/ports/UPDATING before upgrading with portmaster.

SystemCommandNotes
Debian / Ubuntusudo apt-get upgradeOnly upgrades installed packages, where possible.
sudo apt-get dist-upgradeMay add or remove packages to satisfy new dependencies.
sudo apt upgradeLike apt-get upgrade.
sudo apt full-upgradeLike apt-get dist-upgrade.
CentOSsudo yum update
Fedorasudo dnf upgrade
FreeBSD Packagessudo pkg upgrade
FreeBSD Portsless /usr/ports/UPDATINGUses less to view update notes for ports (use arrow keys to scroll, press q to quit).
cd /usr/ports/ports-mgmt/portmaster && sudo make install && sudo portmaster -aInstalls portmaster and uses it to update installed ports.

Find a Package

Most distributions offer a graphical or menu-driven front end to package collections. These can be a good way to browse by category and discover new software. Often, however, the quickest and most effective way to locate a package is to search with command-line tools.

SystemCommandNotes
Debian / Ubuntuapt-cache search search_string
apt search search_string
CentOSyum search search_string
yum search all search_stringSearches all fields, including description.
Fedoradnf search search_string
dnf search all search_stringSearches all fields, including description.
FreeBSD Packagespkg search search_stringSearches by name.
pkg search -f search_stringSearches by name, returning full descriptions.
pkg search -D search_stringSearches description.
FreeBSD Portscd /usr/ports && make search name=packageSearches by name.
cd /usr/ports && make search key=search_stringSearches comments, descriptions, and dependencies.

View Info About a Specific Package

When deciding what to install, it’s often helpful to read detailed descriptions of packages. Along with human-readable text, these often include metadata like version numbers and a list of the package’s dependencies.

SystemCommandNotes
Debian / Ubuntuapt-cache show packageShows locally-cached info about a package.
apt show package
dpkg -s packageShows the current installed status of a package.
CentOSyum info package
yum deplist packageLists dependencies for a package.
Fedoradnf info package
dnf repoquery --requires packageLists dependencies for a package.
FreeBSD Packagespkg info packageShows info for an installed package.
FreeBSD Portscd /usr/ports/category/port && cat pkg-descr

Install a Package from Repositories

Once you know the name of a package, you can usually install it and its dependencies with a single command. In general, you can supply multiple packages to install simply by listing them all.

SystemCommandNotes
Debian / Ubuntusudo apt-get install package
sudo apt-get install package1 package2 ...Installs all listed packages.
sudo apt-get install -y packageAssumes “yes” where apt would usually prompt to continue.
sudo apt install packageDisplays a colored progress bar.
CentOSsudo yum install package
sudo yum install package1 package2 ...Installs all listed packages.
sudo yum install -y packageAssumes “yes” where yum would usually prompt to continue.
Fedorasudo dnf install package
sudo dnf install package1 package2 ...Installs all listed packages.
sudo dnf install -y packageAssumes “yes” where dnf would usually prompt to continue.
FreeBSD Packagessudo pkg install package
sudo pkg install package1 package2 ...Installs all listed packages.
FreeBSD Portscd /usr/ports/category/port && sudo make installBuilds and installs a port from source.

Install a Package from the Local Filesystem

Sometimes, even though software isn’t officially packaged for a given operating system, a developer or vendor will offer package files for download. You can usually retrieve these with your web browser, or via curl on the command line. Once a package is on the target system, it can often be installed with a single command.

On Debian-derived systems, dpkg handles individual package files. If a package has unmet dependencies, gdebi can often be used to retrieve them from official repositories.

On CentOS and Fedora systems, yum and dnf are used to install individual files, and will also handle needed dependencies.

SystemCommandNotes
Debian / Ubuntusudo dpkg -i package.deb
sudo apt-get install -y gdebi && sudo gdebi package.debInstalls and uses gdebi to install package.deb and retrieve any missing dependencies.
CentOSsudo yum install package.rpm
Fedorasudo dnf install package.rpm
FreeBSD Packagessudo pkg add package.txz
sudo pkg add -f package.txzInstalls package even if already installed.

Remove One or More Installed Packages

Since a package manager knows what files are provided by a given package, it can usually remove them cleanly from a system if the software is no longer needed.

SystemCommandNotes
Debian / Ubuntusudo apt-get remove package
sudo apt remove package
sudo apt-get autoremoveRemoves unneeded packages.
CentOSsudo yum remove package
Fedorasudo dnf erase package
FreeBSD Packagessudo pkg delete package
sudo pkg autoremoveRemoves unneeded packages.
FreeBSD Portssudo pkg delete package
cd /usr/ports/path_to_port && make deinstallDe-installs an installed port.

The apt Command

Administrators of Debian-family distributions are generally familiar with apt-get and apt-cache. Less widely known is the simplified apt interface, designed specifically for interactive use.

What Is Apt-key For Macos Windows 10

Traditional Commandapt Equivalent
apt-get updateapt update
apt-get dist-upgradeapt full-upgrade
apt-cache search stringapt search string
apt-get install packageapt install package
apt-get remove packageapt remove package
apt-get purge packageapt purge package

While apt is often a quicker shorthand for a given operation, it’s not intended as a complete replacement for the traditional tools, and its interface may change between versions to improve usability. If you are using package management commands inside a script or a shell pipeline, it’s a good idea to stick with apt-get and apt-cache.

Get Help

In addition to web-based documentation, keep in mind that Unix manual pages (usually referred to as man pages) are available for most commands from the shell. To read a page, use man:

In man, you can navigate with the arrow keys. Press / to search for text within the page, and q to quit.
