Humm... thanks for the new link. From the screenshot, you will be installing a 64 bit version which is not recommended by Microsoft as it will cause problems with plugins, please consider change it to 32 bit even your are on 64 bit OS.
The code:
setup.exe /configure configuration-Office2019Enterprise.xml
You need a bit of flexibility here, anyway it should work. Just want to make sure that you have the right edition, which edition did you buy? If it is not Pro Plus, comment below and I will get you a new code, if it is Pro Plus, then you are all good.
