A few people have found their recent updates haven’t delivered as expected. Don’t forget *all* of the pre-req’s. The Office 2013 SP1 requirement still applies if you’re using Outlook 2010, as Lync 2013 in all of its flavours – e.g. Lync Basic – is still a component of Office 2013.



Current Version


Microsoft Office 2013 Service Pack 1 (KB2817430) 1.0 18 February 2014
Update for Office 2013 (KB3054853) (NOTE 1 BELOW) 1.0 9 June 2015
LyncHelpLoc (Kb3039776) 1.0 1 December 2015
Microsoft Office 2013 Language Pack Service Pack 1 (KB2817427) 1.0 13 February 2014

NOTE1: “You do not have to apply update KB3054853 if you applied the April 14, 2015, update (KB2889923) or the May 12, 2015, security update (KB3039779) for Lync 2013 (Skype for Business)”


This is the client fix itself:

  • x86 (lync2013-kb3115033-fullfile-x86-glb.exe)
  • x64 (lync2013-kb3115033-fullfile-x64-glb.exe)


I have all the pre-req’s already installed, so a reboot was not required. I was however running Outlook 2013 at the time and I was prompted to exit it, to which I duly complied.
