I want to downgrade my Office 365, from Version 1810, Build 11001.20108 to Version 1809, Build 10827.20138 / 16.0.10920.20003

Tried to downgrade with two methods - but both without success:

  1. a bat-file, containing cd %programfiles%\Common Files\Microsoft Shared\ClickToRunofficec2rclient.exe /update user updatetoversion=16.0.10920.20003
  2. Download and run Deployment Tool with custom confifuration file, edited to

<Configuration> <Updates Enabled="TRUE" TargetVersion="16.0.10920.20003" /> </Configuration>

Could somebody point me to any working method?

Update (could be important): i'm not an administrator, and the Microsoft user, which gets updates, is shared between multiple terminals. Thats why i'm forced to operate only on my computer - operating under Microsoft user would make changes on some terminals beside of mine.

  • Are you an Administrator of your Office 365 deployment? – Ramhound Dec 3 '18 at 12:07
  • no, and the user, which gets updates is shared by multiple clients (not only my computer). It means, i can operate only on my computer - because if i operate with Microsoft user the changes would apply on other terminals too. – Evgeniy Dec 3 '18 at 12:19
  • If you are not an Administrator of your Office 365 deployments then you don’t have access to what you need to accomplish your task. – Ramhound Dec 3 '18 at 12:34
  • As long as you are an Administrator on the machine you might be able to use the deployment tool but you are going to fight the Office 365 deployment configuration so the modified installation likely will be updated – Ramhound Dec 3 '18 at 12:46
  • What do i need as an Office-Administrator to roll back? Maybe i'll be able to get my admin to cooperate... – Evgeniy Dec 3 '18 at 13:13

As Ramhound says, to revert to an earlier version of click-to-run Office 2016 on the computer, it requires Administrator to do it. We can follow the steps below to revert it:

See Microsofts official documentation here

In Short:

  1. Download the Office Deployment Tool.
  2. Install and extract it to a ODT folder in Desktop. It contains two files: Setup.exe and Configuration.xml.
  3. Open Configuration.xml file, edit it with the following text, then save it as a new file RevertOffice.xml in the same folder of Setup.exe:

<Configuration> <Updates Enabled="TRUE" TargetVersion="16.0.10920.20003" /> </Configuration>

  1. In Windows, click Start, search for cmd, right-click Command Prompt, click Run as Administrator.
  2. Switch to the file location for the Setup.exe file. For example, type cd C:\Users\Administrator\Desktop\ODT
  3. Run the following command: setup.exe /configure RevertOffice.xml
  4. Start Word 2016, go to File > Account, under Product Information, click Update Options > Update Now.
  5. Check if the Office is reverted to your targeted version.
  6. Disable Office Update to avoid it update to higher version: In Word 2016, click File > Account, under Product Information, click Update Options > Disable Updates.
  • as i written in the question, i've tried this method already, without success. – Evgeniy Dec 6 '18 at 10:17
  • @Evgeniy Are you tried the steps above with the local administrator account on the computer? – WinniL Dec 7 '18 at 2:48
  • Sure, des, tried it – Evgeniy Dec 7 '18 at 6:27
  • This worked a treat. Had to downgrade from a current monthly security release to the previous month's due to a software incompatibility with Office 365. Executed this script as shown, other than the version change, and it worked first time, perfectly. Thanks @winnil – mike.thorn Nov 15 '19 at 18:49

I tried the other techniques, but couldn't make them work.

This simple command does the trick for me though:

"C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe" /update user updatetoversion=16.0.10827.20181

i do it yesterday, from ver 1904 to 1903...license bussiness premium

that not work for me....after varoius atempts i have to do it from zero

  • uninstall office
  • download deployment tool
  • use https://config.office.com/officeSettings/configure# to configure the xml (here you can choose a pair of versions to downgrade)
  • use first, "setup /download" to download locally
  • then use "setup /configure" to install

but im interesting in doing directly...
