Custom installation of Office

First, you’ll need to clear previous installations of Office. You can skip this if Office has never been installed on the machine before:

Uninstall Office with the App and Features option in Windows settings.
Run OfficeScrubber.cmd file from Office Scrubber by abbodi1406 and select [R] Remove all Licenses option.

Once you’re done:

Download Office Deployment Tool (ODT)
Copy the downloaded setup.exe file to the root of the C drive, i.e. C:\setup.exe.
Go to config.office.com
If you want Retail Office then select Microsoft 365 Apps for enterprise in the office suites section.
If you want Volume Office then select Office LTSC Professional Plus 2021 - Volume License in the office suites section. (Don’t select the SPLA version)
You can add Visio and Project apps if you need them. Don’t select language that is not available for Project/Visio if you are installing those apps.
Customize other things and leave settings as default if you don’t understand something.
Once you go through all the options, click on the export button, select “Keep Current Settings” option and it will download a file named Configuration.xml
Copy the downloaded 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 /
.\setup.exe /configure .\Configuration.xml
```

It will now download and install Office. You can activate it with your preferred method.
