Office Pro Plus 2019 Installation Guide

Office Pro Plus 2019 stands as a perpetual Office edition, accessible via a product key for installation on a single PC. It links to a Microsoft account for subsequent installations, even on a different PC, provided only one active installation is maintained. For reinstalls, simply sign in with the associated Microsoft account to activate Office automatically. This configuration is favored by businesses due to its commercial license validity, while individuals appreciate the traditional, non-subscription, lifetime Office model.

Please be aware that Office Professional Plus 2019 does not support Mac systems. If you require Microsoft Office compatible with both Windows and Mac, and capable of activation across up to 5 PCs or Macs, along with an additional 5 Tablets, Androids, or iPhones, we recommend considering Office 365.
