Office 2016 Mac Catalina Serializer

19.02.2021

Soon Microsoft are to release an update to the Office 2016 Volume License installer on VLSC.

This update is 15.17 & is the first that has a few changes that may affect the way you deploy Office 2016. Convert pdf to jpg for free.

Microsoft recently released a new software installer to help make the task of deploying updated copies of Office 2016 for Mac admins a lot easier. This new installer is available along with the latest Office 2016 volume license installer and is named MicrosoftOffice2016VLSerializer.pkg. With Office 2016, Microsoft are moving to a device based serialisation method. Which means that deploying the plist /Library/Preferences/com.microsoft.office.licensingv2.plist will no longer work. This device based serialisation is based around the generating a license on the Mac that is to be running Office 2016.

These changes are going to be later enforced in 15.20 & onwards. Below are some details on the changes, some of the why & how via the power of the MacAdmins.org Slack & the awesome @pbowden that some of us have had a sneak peek.

  1. Jun 21, 2016 Microsoft Office 2016 VL ProPlus ISO Download first release of Microsoft office was held in 1988 by Bill Gates. In this office suit they includes Microsoft Word 2016, PowerPoint and MS Excel 2016 which was very useful for office work. Yes, you can install and use Office 2016 for Mac and Office for Mac 2011 at the same time.
  2. Office 2011 and older versions of Microsoft Office simply do not run in Catalina. They are 32-bit. Apple stops support for 32-bit apps with Catalina. See How to Set up Your Catalina Mac to Run 32-bit apps. Alternatively, you can restore your Mac to pre-Catalina. Restore your Mac from a backup - Apple Support. Microsoft Office 2016 16.16.26.
  3. Important: In order to upgrade to Microsoft 365 or Office 2019, your Mac needs to meet the minimum operating system and hardware requirements. With the release of macOS 10.15 Catalina, Microsoft 365 for Mac and Office 2019 for Mac currently support macOS 10.15, 10.14, and 10.13. For more information, see this article.

  • 1 What’s Changing?

When you download the .iso from VLSC you’ll notice two packages within it:

The change is the new second pkg: “Microsoft_Office_2016_VL_Serializer.pkg”

What’s that about?

Well, for a while now it’s been fairly common practice to deploy the Office license to Macs outside of the Office installers or updates.

This came about as on occasion an Office Update or Installer would delete the file.

However, whilst the deletion itself was a bug, the ability to use the license.plist across Macs was also a bug.

What is it & should I use it?

With Office 2016, Microsoft are moving to a device based serialisation method. Which means that deploying the plist /Library/Preferences/com.microsoft.office.licensingv2.plist will no longer work.

This device based serialisation is based around the generating a license on the Mac that is to be running Office 2016.

So if you employ monolithic imaging or deploy Office 2016 via a Composer snap shot etc, the serialisation will not work. (Please don’t deploy Office 2016 via a Composer snap shot, use the pkg).

Also, if you install Office 2016 whilst booted to another volume (as in when installing via a NetBoot or NetInstall volume or something like Target Mode Imaging), again the serialisation will not work.

To install Office 2016 from another volume & have the serialisation work, cache it locally on the Mac being imaged & install on first boot or if using Casper Imaging check “Install on boot drive after Imaging” for the PKG from within Casper Admin.

However, to enable Office 2016 to be correctly licensed in the multitude of deployment scenarios that we mac admins employ, @pbowden & his team have created the “Microsoft_Office_2016_VL_Serializer.pkg”

Running this will correctly serialise the Office 2016 suite, & should be run from the Mac that’s running the suite. So again, can be added post imaging & then the suite will be correctly serialised.

To be clear, this will only affect you if using the Volume Licensed version of Office 2016 & not the Office365 version.

Office For Mac Serializer

What happens if I carry on copying the licensing.plist?

For now, not much.

15.17 is the first release with the “Microsoft_Office_2016_VL_Serializer.pkg”, from 15.20 (scheduled for Q1 2016) you will have to use the correct license.

Office Mac Serializer 2019

How did people find this out?

Office 2016 Mac Catalina Serializer

Well a little over a month ago a gentleman with the nick @pbowden hopped into the #microsoft-office channel on the MacAdmins.org Slack, this was awesome as @pbowden is a: Software engineer for Office for Mac/iOS at Microsoft, a fellow Brit & nice guy.

It’s been a great few weeks with the community sharing feedback with @pbowden & some of us being able to test pre-release installers for Office.

I hope this warning has been as helpful to you, as it was when @pbowden shared it with us.
