rit, the command is not doing the trick since its already full version,
PS C:\Users\lyncadmin> Get-CsServerVersion
Microsoft Lync Server 2013 (5.0.8308.0): Volume license key installed.
only one server in one pool, total two pools.
Lync 2013 is on Win 2008 R2, and the event in system im inclining to since i have tried all,
