Installation Manager

You can use IBM® Installation Manager to install, update, and modify IBM® software packages. You can also track what you installed, determine what is available to install, and organize installation directories.

Installation Manager provides tools to update, modify, and uninstall packages and to manage the licenses for your packages:

Install packages: Use the Install wizard to complete the installation process. You can install a package by accepting the defaults or you can modify the default settings to create a custom installation. Before you install the package, you can review a complete summary of your selections throughout the wizard. You can install one or more packages at one time.
Update packages: Use the Update wizard to search for available updates to packages that you have installed. An update might be a released fix, a new feature, or a new version of the product. The wizard provides details of the update. You can choose whether to apply an update.
Modify packages: Use the Modify wizard to modify certain elements of a package that you have installed. During the first installation of the package, you select the features to install. Later, if you need other features, you can use the modify packages wizard to add those features to your package. You can also remove features and add or remove languages.
Manage licenses: Use the Manage Licenses wizard to set up the licenses for your packages. Use this wizard to change your trial license to a full license, set up servers for floating licenses, and select the type of license for each package.
Roll back to an earlier version: Use the Roll Back wizard to revert to a previous version of a package.
Uninstall packages: Use the Uninstall wizard to remove a package from your computer. You can uninstall more than one package at a time.
