Installing Servers (Command Line)

Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

The primary installation file for Office Communications Server is the Server.msi file. This file installs or uninstalls Standard Edition, Enterprise Edition, Proxy Servers, and Edge Servers. As mentioned earlier, the command-line parameters you supply when you run an .msi file are for the MSIExec application, not the .msi file. This is not entirely true. Because the same setup file is used for all of these servers, Server.msi has its own set of parameters:

  • Server. This parameter is required and must be set to one of the following (these values are case-sensitive):

    • SE Standard Edition

    • EE Enterprise Edition

    • AP Edge Servers

    • PROXY Proxy Servers

  • SKU. This parameter is required when installing a Proxy Server or an Edge Server. Possible values are SE (Standard Edition) and EE (Enterprise Edition). This value must match the type of product key you will provide during installation. (These values are also case-sensitive.)

Launch Server.msi with the following syntax.

MsiExec.exe /i Server.msi SERVER={SE|EE|AP|PROXY} SKU={SE|EE} [Optional Msiexec.exe Parameters]

Such as:

Msiexec.exe /i Server.msi SERVER=SE /l*v C:\SE.log


Msiexec.exe /i Server.msi SERVER=PROXY SKU=SE /l*v C:\Proxy.log

An installation wizard appears and prompts you through the process.


Installation requires Unified Communications Managed API 2.0 Redistributable and Microsoft Office Communications Server Core Components to be installed in advance. From within the Office Communications Server installation disc, locate and run both UcmaRedist.msi and OCSCore.msi.
