Procedure

1. Record the logon credentials for each computer. OfficeScan will prompt you to specify the logon credentials during installation.
2. The OfficeScan client will not be installed on a computer if:
   • The OfficeScan server is installed on the computer.
   • The computer runs Windows XP Home, Windows Vista Home Basic, Windows Vista Home Premium, Windows 7™ Starter, Windows 7 Home Basic, Windows 7 Home Premium, and Windows 8 (basic versions). If you have computers running these platforms, choose another installation method. See Deployment Considerations for details.
3. If the target computer runs Windows Vista (Business, Enterprise, or Ultimate Edition) Windows 7 (Professional, Enterprise, or Ultimate Edition), Windows 8 (Pro, Enterprise), or Windows Server 2012 (Standard), perform the following steps on the computer:
   1. Enable a built-in administrator account and set the password for the account.
   2. Disable the Windows firewall.
   3. Click Start → Programs → Administrative Tools → Windows Firewall with Advanced Security.
   4. For Domain Profile, Private Profile, and Public Profile, set the firewall state to "Off".
   5. Open Microsoft Management Console (click Start → Run and type services.msc) and start the Remote Registry service. When installing the OfficeScan client, use the built-in administrator account and password.
4. If there are Trend Micro or third-party endpoint security programs installed on the computer, check if OfficeScan can automatically uninstall the software and replace it with the OfficeScan client. For a list of client security software that OfficeScan automatically uninstalls, open the following files in <Server installation folder>\PCCSRV\Admin. You can open these files using a text editor such as Notepad.
   • tmuninst.ptn
   • tmuninst_as.ptn
   If the software on the target computer is not included in the list, manually uninstall it first. Depending on the uninstallation process of the software, the computer may or may not need to restart after uninstallation.
