Lync 2013 with Office Web Apps Server

After instalation of the Office Web Apps Server and integration with Lync 2013 you might find out that Lync 2010 clients can upload and view powerpoints but Lync 2013 clients do not.

You might see this error on the Lync FE:

Syncing Office Web Apps Server with legacy presenters failed, newer clients may have lost sync for PowerPoint presentations driven by the legacy clients.

Microsoft documentation says you need to install these:

Add-WindowsFeature Web-Server,Web-Mgmt-Tools,Web-Mgmt-Console,Web-WebServer,Web-Common-Http,Web-Default-Doc,Web-Static-Content,Web-Performance,Web-Stat-Compression,Web-Dyn-Compression,Web-Security,Web-Filtering,Web-Windows-Auth,Web-App-Dev,Web-Net-Ext45,Web-Asp-Net45,Web-ISAPI-Ext,Web-ISAPI-Filter,Web-Includes,InkandHandwritingServices

But there's a few features missing for this to work

Add-WindowsFeature NET-Framework-Features, NET-Framework-Core, NET-HTTP-Activation, NET-Non-HTTP-Activ, NET-WCF-HTTP-Activation45

Add this ones, restart the Office Web Apps service and everything should be working now!
