The one-time installation has no upgrade options for future Office releases in terms of pricing. As you recall, I mentioned Microsoft has made it less desirable to download and install this Office variant. Essentially, when you download Office 2019, it is a one-time purchase that means you pay a single, up-front cost for getting the Office applications delivered on your computer. Microsoft has a nice article found here that goes into the details of the differences between Office 2019 and Office 365 delivered applications. Let’s take a look at Office 2019 vs Office 365 Differences and Installation.
Recently, with my Visual Studio subscription, I wanted to take a closer look at the differences between the two as well as the installation process between the versions. They have also made it increasingly less desirable to install the full Office 2019 local install as opposed to the Office 365 delivered apps for the Office installation. In fact, Office 2019 has been said by Microsoft to be the last full install of Office 2019. Microsoft is now delivering their Office line of products via the Office 365 subscription model.
There is no doubt that today’s software companies are moving to a “software-as-a-service” model instead of a perpetual licensing model for locally installed software.
