Uninstalling the OfficeScan (OSCE) server

To uninstall the OfficeScan server using the uninstallation program:

1. If you performed a fresh installation on the server computer, proceed to step 2.

   If you upgraded the server from an earlier version of OfficeScan, do any of the following:

   1. Uninstall the Plug-in Manager if it is installed.
   2. If the Plug-in Manager is not installed, delete the AOS registry key located in: HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\OfficeScan\service\.
    

   Always back up the whole registry before making any modifications. Incorrect changes to the registry can cause serious system problems.
2. Run the uninstallation program. There are two ways to access this program:

   2. Click Yes. The server uninstallation program prompts you for the administrator password.
   3. Type the admin password and then click OK. The server uninstallation program will then start removing the server files. A confirmation message will appear.
   4. Click OK to close the uninstallation program.

   Option 2

   1. Go to Control Panel > Add or Remove Programs.
   2. Look for and double-click Trend Micro OfficeScan Server.
   3. Follow the on-screen instructions until you are prompted for the administrator password.
   4. Type in the admin password and then click OK. The server uninstallation program starts removing the server files. A confirmation message will appear afterwards.
