Lync 2013 is out, along with a new set of demands to install it right on your Windows Server.

Here’s how to get it done:

First, install the roles and features required:
Import-Module ServerManager
Add-WindowsFeature Web-Dyn-Compression,desktop-experience,RSAT-ADDS,Web-Server,Web-Scripting-Tools,Web-Windows-Auth,Web-Asp-Net,Web-Log-Libraries,Web-Http-Tracing,Web-Stat-Compression,Web-Default-Doc,Web-ISAPI-Ext,Web-ISAPI-Filter,Web-Http-Errors,Web-Http-Logging,Web-Net-Ext,Web-Client-Auth, Web-Filtering,Web-Mgmt-Console,Msmq-Server,Msmq-Directory

Then, Install .Net 4.5 Framework (Download).

Next, install Windows Identity Foundation (Download) and Windows Management Framework 3.0 (Download) that contains PowerShell 3.0.

You might also have to download and install KB2646886.

Windows Server 2012 and Windows Server 2012R2:

Make sure you have the Windows Server installation CD or source. It’s required to install ,Net 3.5 Framework.

Then, from an elevated PowerShell, run the following command:

Note: You don’t need to run “Import-Module ServerManager”, Windows 2012 loads the modules automatically

To avoid Event IDs 32402, 61045 on Lync 2013 Front End Servers (See KB2901554), run the following from an elevated command prompt:

Reg Add "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SecurityProviders\Schannel" /V "EnableSessionTicket" /D 2 /T REG_DWORD /F

Now you’re all ready to install Lync Server 2013.
