How to install the update

To install the cumulative update for Lync Server 2013 Unified Communications Managed API 4.0 Runtime, 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 UI or a command line.

    Note When you click Install Updates, the UI provides a clear indication of which updates are installed.

    To run the Installer, run the following command:

    LyncServerUpdateInstaller.exe

    Note You can use the following parameters 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, and then it 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" in the folder from which you ran the command.

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