Please note that in the official C2R VL office installation method, there is no ISO or any one-click solution available. Below is the simplest guide to installing VL office.
First clear previous installation of Office,
Uninstall the office with App and Features option in Windows settings.
Run OfficeScrubber.cmd

Office was never installed on the system.
Once done,

the C drive, i.e. C:\setup.exe
Goto config.office.com
Select

(Don’t
select SPLA version) in the office suites section. You can add Visio and
Project apps if you need them. Customize other things and leave them as
default where you don’t understand something. Don’t select language
which is not available for
Project/Visio if you are installing these apps.
Once you go through all the options, click on the export button
and it will download a file named
Configuration.xml

file to the
root of the C drive, i.e. C:\Configuration.xml
Open the command prompt as admin and run the below commands
cd /d C:\
setup.exe /configure Configuration.xml
It will now download and install Office. You can activate it with your preferred method.
