This download of Microsoft Office Professional 2019 is used to install full 2019 versions of Microsoft Word, Excel, PowerPoint, Outlook, Publisher, and Access, plus additional OneNote features on a single Windows computer. This suite is designed to help you create and organize faster with time-saving features, a modern look, and built-in collaboration tools. While Internet access is required to install Office, you do not need to be connected to the Internet to use the Office applications.
Please be aware that Office 2019 is a one-time purchase that comes with classic apps like Word, Excel, and PowerPoint for Windows, and does not include any of the services that come with an Office 365 subscription. One-time purchases don't have an upgrade option, which means if you plan to upgrade to the next major release, you'll have to buy it at full price. Also, please be aware that the OneNote features vary.
