The Trend Micro OfficeScan client can be installed on a workstation via the network (using an UNC-path) through the AutoPCC utility. The client can simply browse the OfficeScan server, locate the autopcc.exe utility, and run it, performing an installation of the OfficeScan client on the computer running the utility. By default, the installation of the client is not silent, meaning the user will see windows and dialogs appearing. Fortunately, it is possible to make AutoPCC to perform the installation completely silently, leaving the user almost unaware that an installation of OfficeScan is occurring.

1. To change this setting, log on to the OfficeScan server, and browse to the OfficeScan install directory (wherever you've installed it). This usually corresponds with wherever the share serverofcscan is pointing to (by default: %PROGRAMFILES%Trend MicroOfficeScanPCCSRV).
2. In that folder, browse the Autopcc.cfg folder, and open the file AutoPCC.INI with Notepad.
3. Locate the [Install] section and make the following changes:
4. Save and close the file. Perform the installation on the client using the AutoPCC utility. A command prompt will appear during the installation and will automatically disappear once the installation has been completed.
