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

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-kb3115261-fullfile-x86-glb.exe)
  • x64 (lync2013-kb3115261-fullfile-x64-glb.exe)


Alas, in my enthusiasm to get this update installed I failed to exit the client first, so yes I was prompted for a reboot!


A re-run of the process on another PC resulted in the update going on without any requirement to reboot.
