Revert to a specific MS Office version using PowerShell on a "start with 1-click" install

Question

I used sometimes ago a PowerShell command that makes an installed version of MS Office to revert to an older version, any of those referenced at Update history for Office 2013

But I don't remember the command, can you help?

The procedure was to launch PowerShell as an admin.
Then execute a command starting from somewhere into C:\Program Files\Microsoft Office 15\root\office15\ and ending with =[the version you want to go to] (like =15.0.4823.1004)

Answer 1

It's %programfiles%\Microsoft Office 15\ClientX64\OfficeC2RClient.exe /update user updatetoversion=15.0.4823.1004, this will only work with Click-to-Run installations of Office.
