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.
The size of the upgrade package displays beside the Download button.
Navigating away from the screen during the download does not affect the upgrade.
If OfficeScan encounters problems downloading or installing the package, check the server update logs on the OfficeScan web console. On the main menu, click Logs > Server Update.
After the upgrade, the Plug-in Manager service may need to restart, causing the Plug-in Manager screen to be temporarily unavailable. When the screen becomes available, the current plug-in program version displays.
