I have download Office Professional Plus 2019 from Microsoft Volume Licensing Service Center today. I'm running the setup on a fresh Windows 10 build 1809, and I get this error message at the begining of the setup :

"Setup is unable to proceed due to the following error(s): This product requires Internet Information Services (IIS) 7.0 or higher., with ASP .NET v4.0 in the list of IIS Web Server Extensions. Correct the issue(s) listed above and re-run the setup."

If I add the feature Internet Information Services (abnormal for an Office setup), I can get trought the installation. BUT I got some kind of Microsoft Office Online Server installed, no Office applications. Any clue? Thank you!

(sorry my horrible english, I speak french)

Sounds like you downloaded the wrong thing. Microsoft has "office online" installers that set up web based apps similar to O365 web apps, for use with on-prem sharepoint servers or similar. Sounds like you downloaded that instead of proplus. Which explains its need for IIS.

Online Server is used to deliver browser based versions of office, but if you have a volume license there is no need to use that. See the below link for more info an review the type of license you have:

I finaly need to use Office 2019 Deployment Tool with a predefined XML file to download and install Office 365 (...). Seem that there is no conventional ISO, with a setup.exe and all the file needed, for Office 2019.

Thank you Cliff Galiher for making me realise that I download the wrong thing. It was under the Office Pro Plus 2019 section, I didn't pay attention. Thank you all!

Office 2019 is indeed only available via C2R.  MSI (and the setup.exe that wrapped it) is gone.

You admit that my answer was accurate, but no credit given.  Odd.
