Pre-Req’s

It’s been a big year for pre-req updates, but if you’re current then you’re OK today.

If however your patching isn’t to current you’ll need to check you have *all* of these pre-req’s. The Office 2013 SP1 requirement still applies if you’re using Outlook 2010. (Lync 2013 in all of its flavours – e.g. Lync Basic – is still a component of Office 2013).
