MSI Prerequisites for the Installer

In all Windows operating environments, the Installer of CA ITCM requires the Microsoft Windows Installer (MSI) engine 2.0. If this version is not available, the installation wizard installs it automatically prior to any installation step. The upgrade to MSI 2.0 does require a system reboot.

On Windows 2003 systems, reboots are very unlikely to happen, as MSI 2.0 should have been installed as part of the operating system.
