Plug-in Program Upgrades
A new version of an installed plug-in program displays on the Plug-in Manager console. Download the package and upgrade the plug-in program on the console. Plug-in Manager downloads the package from the Trend Micro ActiveUpdate server or a custom update source, if one has been properly set up. An Internet connection is necessary to download the package from the ActiveUpdate server.
When Plug-in Manager downloads an installation package or starts an upgrade, Plug-in Manager temporarily disables other plug-in program functions such as downloads, installations, and upgrades.
Plug-in Manager does not support plug-in program upgrading using the Trend Micro Control Manager single sign-on function.
