Office 2019 includes new perpetual versions – where the license is purchased outright and effectively has no expiry date – includes Access, Excel, OneNote, Outlook, PowerPoint, Publisher, Word, and Skype for Business.
There isn’t a new 2019 version of OneNote, but an understanding of OneNote is installed with Office 2019. For more information, see the Deployment Guide for OneNote.
All products in Office 2019 are available in both 32-bit and 64-bit versions. We recommend 64-bit on computers that have 4 GB or more of memory. But you should assess application compatibility and other factors that might require you to use the 32-bit version. For more information, see Choose between the 64-bit or 32-bit version of Office.
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.
