There is no way out there to install Office 2019 on Windows 7 or Windows 8/8.1. Here's what you need to know if you're upgrading to Office 2019. But, there's a big change with this new product line. On PCs, you’ll need Windows 10 for Office 2019 as Microsoft will not support any versions of Windows 7 or 8. It was released to general availability for Windows 10 and for macOS on September 24, 2018. Microsoft Office 2019 is the current version of Microsoft Office, a productivity suite, succeeding Office 2016.
