Jul 24, 2017 Per my research, w hen you download SharePoint Server 2016 from here, you will see that it states it is RTM (16.0.4351.1000). After the installation, the farm will show you the wrong build version number 16.0.4327.1000, which is a Release Candidate build number. This is not an bug, The farm build number may not increment. If you're the Office 365 admin of an Office for business plan, users in your organization can only install Office using the steps in this topic as long as your plan includes the desktop version of Office, and you've assigned the user a license and given them permission to install Office (Manage software download settings in Office 365).
When you are installing an Exchange 2013 server, or upgrading it with a cumulative update, you may encounter a warning message regarding the Office Filter Pack not being installed.
This computer requires the Microsoft Office Filter Packs – Version 2.0. Please install the software from…
This computer requires the Microsoft Office 2010 Filter Packs – Version 2.0 – Service Pack 1. Please install the software from…
These are warning messages and do not block the installation or upgrade of Exchange 2013. The Office Filter Pack is not a mandatory Exchange 2013 pre-requisite.
The Exchange 2013 pre-requisites page on TechNet, at the time of this writing, does include the Office Filter Packs as a step in the preparation of a server for Exchange 2013. What it doesn't make clear is that they are not required.
The new Exchange Search already has support for indexing/searching Office file types, as well as a series of other file types including some third party formats such as PDF. You can see a full list here.

So should you install the Office Filter Pack? If you want to stop seeing that warning message, then yes. If you want to take the approach of only installing required software on your servers, then no. Consider also that installing it means potentially having to update it later on if there is a bug fix or a security issue.
