The Installer for Windows (Installer) is a software management component that resides on the Windows target computers in the network. You install it on the target computers as part of the software delivery agent functionality.
The Installer receives, installs, and removes SXP products. The Installer lets you easily upgrade and downgrade installed software products, without the need to uninstall or remove older products manually before upgrading or downgrading. The installed product is automatically completely uninstalled by the Installer, before the new product version is installed on the target computer.
The Installer for Windows consists of two main components, the Installer function and the Logon function.
The Installer function checks for pending install or uninstall jobs from a manager, and executes them. However, the Installer cannot directly execute the user-defined settings, for example, from the ureg.sxp and ulinks.sxp files. Instead, it prepares these files for execution by the Logon function.
The Logon function implements the treatment of user-defined settings for the installed products. Because many settings can be processed only if the user is actually logged on, the Logon function is started automatically when the user logs on.
The Logon function can also be configured to interact directly with the Installer, so that settings can be processed immediately for the current user.
