How to install the update

This cumulative update improves the reliability, stability, and performance of Microsoft Lync Server 2013 Persistent Chat. To install the cumulative update, use one of the following methods:

Method 1: Cumulative Server Update Installer

The Cumulative Server Update Installer applies all updates for the appropriate server role in one operation. To use the Cumulative Server Update Installer, follow these steps:

Note If User Account Control (UAC) is turned on, you must start the Cumulative Server Update Installer by using elevated permissions to make sure that all updates are installed correctly.

  1. Download the Cumulative Server Update Installer.

  2. Run the Cumulative Server Update Installer by using the user interface (UI) or by using a command line.

    Note When you click Install Updates, the UI indicates which updates are installed.

    To run the Cumulative Server Update Installer, run the following command: LyncServerUpdateInstaller.exe Note The following text describes parameters that you can use together with the LyncServerUpdateInstaller.exe command:

    • The /silentmode switch applies all applicable updates in the background.

    • The /silentmode /forcereboot switch applies all applicable updates in the background. Additionally, the switch automatically restarts the server at the end of the installation process if this is necessary.

    • The /extractall switch extracts the updates from the installer and saves the updates in a subfolder that's named "Extracted." The subfolder is in the folder in which you ran the command.

After you run the Cumulative Server Update Installer, you must update all the applicable back-end servers. See how to update the back-end servers.
