And depending on how you intend to use your Office apps, their 64-bit versions might work better than the 32-bit ones. One reason why you might want Office 64-bit is that you prefer to be as up-to-date as possible. Moreover, as Microsoft is one of the world's largest software companies, many programs developed by them, including Office, are available both in 32-bit and 64-bit versions. Among other things, this leads to a general movement of the software world towards 64-bit apps. Most modern computers, laptops, 2-in-1 devices, tablets, and even smartphones run on 64-bit processors. Which version to download and install: Office 64-bit or 32-bit? Microsoft currently offers a free trial of 30 days. While you can download it for free using certain methods, you can only install and use it for free for a limited time. NOTE: Microsoft Office is a paid suite of apps, and to be able to use it, you’re required to have an active subscription to Microsoft 365 or a lifetime license for a standalone version of Office.
