How the Installation Process Affects Operating Systems

The CA ARCserve Central Applications installation process updates various Windows operating system components using an installation engine named the Microsoft Installer Package (MSI). The components included in MSI let CA ARCserve Central Applications perform custom actions that let you install or upgrade CA ARCserve Central Applications.

The following table describes the custom actions and the affected components.

Note: All CA ARCserve Central Applications MSI packages call the components listed in this table when you install CA ARCserve Central Applications.

Component	Description
CallAllowInstall	Lets the installation process check for conditions relating to the current CA ARCserve Central Applications installation.
CallPreInstall	Lets the installation process read and write MSI properties. For example, read the CA ARCserve Central Applications installation path from the MSI.
CallPostInstall	Lets the installation process perform various tasks relating to installation. For example, registering CA ARCserve Central Applications into the Windows Registry.
CallAllowUninstall	Lets the uninstallation process check for conditions relating the current CA ARCserve Central Applications installation.
CallPreUninstall	Lets the uninstallation process perform various tasks relating to uninstallation. For example, un-registering CA ARCserve Central Applications from the Windows Registry.
CallPostUninstall	Lets the uninstallation process perform various tasks after the installed files are uninstalled. For example, removing the remaining files.
ShowMsiLog	Displays the Windows Installer log file in Notepad if the end user selects the Show the Windows Installer log check box in the SetupCompleteSuccess, SetupCompleteError, or SetupInterrupted dialogs and then clicks Finish. (This works only with Windows Installer 4.0.)
ISPrint	Prints the contents of a ScrollableText control on a dialog. This is a Windows Installer .dll custom action. The name of the .dll file is SetAllUsers.dll, and its entry point is PrintScrollableText.
CheckForProductUpdates	Uses FLEXnet Connect to check for product updates. This custom action launches an executable file named Agent.exe, and it passes the following: /au[ProductCode] /EndOfInstall
CheckForProductUpdatesOnReboot	Uses FLEXnet Connect to check for product updates on reboot. This custom action launches an executable file named Agent.exe, and it passes the following: /au[ProductCode] /EndOfInstall /Reboot
