We recommend that you uninstall existing versions of Office before you deploy Office 2019. If you’re uninstalling previous versions of Office products that were installed with Windows Installer (MSI), the Office Deployment Tool can remove most of those for you as part of the installation of Office 2019. After downloading the installation files, internet access isn’t required to install, activate, or use Office 2019. There isn’t a 2019 version of SharePoint Designer or InfoPath. The last version for both products is 2013. Office 2019 is a valuable update for customers who aren’t yet ready for the cloud. And each time we release a new on-premises version of Office, customers ask us if this will be our last. We’re pleased to confirm that we’re committed to another on-premises release in the future.
