Although the Office Customization Tool (OCT) is the primary tool for customization installation, administrators can use the Config.xml file to specify additional installation instructions that are not available in the OCT. The following customizations can only be made by using the Config.xml file:

We recommend that you use the Config.xml file to configure Lync 2013 silent installation.

By default, the Config.xml file that is stored in the core product folder (for example, \product.WW) directs Setup to install that product. For example, the Config.xml file in the following folder installs Lync 2013:

The Config.xml elements most commonly used for Lync 2013 installation are listed in the following table.

Config.xml elements

To customize the Config.xml file

  1. Open the Config.xml file by using a text editor tool, such as Notepad.

  2. Locate the lines that contain the elements you want to change.

  3. Modify the element entry with the silent options that you want to use. Make sure that you remove the comment delimiters, "<!--" and "-->". For example, use the following syntax:

    Copy Code
    < DistributionPoint Location="\\server\share\Lync15" />
  4. Save the Config.xml file.
