Deploying Lync 2010... Found these Hotfixes should be installed after installing .Net 3.5, however running each says it is not installed on this system. I am using Server 2008 R2 and .Net 3.5 is listed as installed under features in server manager. Updates show that there are .Net 4 installed. So I am wondering if these files below even need installed anymore for Lync 2010? Thanks!
