I used this as a guide to download and setup the install https://docs.microsoft.com/en-us/deployoffice/office2019/deploy

you can also find and use the OCT (Office Configuration Tool) from this page.

I will use c:\temp for my install setup, this is your choice.

Create your configuration.xml file for the Office product you want to install. 

Download the office setup.exe from your your MSVLSC or other sources.

Run the setup to download the files to package.

setup.exe /download configuration.xml

this will create a subdirectory "office" under c:\temp

modify the configuration.xml and remove the sourcepath from it

save the file and zip the setup, config file and all sub-directories to a zip file.

Upload the zip to the client drop on either the SDA or SMA

for the SDA create a post task and attach the file

For the SMA attach the file to the software inventory.

On the Full Command Line: you MUST use cmd /c to get it to work correctly

cmd /c setup /configure configuration.xml

Note: the SMA will delete the file from the client drop automatically after upload, You must manually delete it from the SDA client drop.
