For organizations using volume licensing, installing differs from retail versions. It utilizes Click-to-Run (C2R) technology rather than traditional MSI installers. To deploy this version, you must use the Office Deployment Tool (ODT) to download and install the software from Microsoft's Content Delivery Network (CDN). Prerequisites for Installation Operating System : Office 2019 requires Windows 10 or newer.
Run the executable and extract its contents into a dedicated folder on your C: drive (e.g., C:\OfficeSetup ). This folder will contain setup.exe and sample configuration files.
You must tell the ODT what to install. Create a new file named configuration.xml in your setup folder using a text editor like Notepad.
