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.
