During the deployment process, the Deployment Wizard for Microsoft Lync Server 2010 automatically installs prerequisite software, based on the role that the server performs in the deployment. If you do not plan to deploy a new Lync Server topology or if no other programs on the computer use this software, we recommend that you remove it. If you deploy a new Lync Server topology and the Deployment Wizard does not detect it on the computer, it reinstalls the prerequisite software.

Tip:
The removal of any other files is optional. It is not required to remove any of the files listed in the following procedure.

To remove prerequisite software installed by Lync Server using the Windows Control Panel

  1. Log on to the computer where Lync Server 2010 was installed as a member of the Local Administrators group.

  2. Click Start, and then click Control Panel.

  3. Click Programs, and then click Programs and Features.

  4. In the list, click each of the following programs, and then click Uninstall.

    Note:
    The list of packages to remove assumes that the server role files have already been removed. If they have not, do not proceed and see Remove Lync Server 2010 Files.

    The listed order should avoid any dependency problems associated with one package relying on another. In rare occasions, removing one package before the package that depends on it may prevent you from removing the dependent package.
