In previous Plug-In Manager versions, the Plug-In Manager installation package is downloaded from the Trend Micro ActiveUpdate server and then installed on the computer that hosts the OfficeScan server. In this version, the installation package is included in the OfficeScan server installation package.

Users who are new to OfficeScan will have both the OfficeScan server and Plug-In Manager installed after running the installation package and completing the installation. Users who are upgrading to this OfficeScan version and have used Plug-In Manager previously will need to stop the Plug-In Manager service before running the installation package.
