If you’re running the Office beta on either Windows 10 or 11, you should be able to turn the redesign on from the Coming Soon pane in Word, Excel, PowerPoint, or OneNote. They’ll also have to uninstall any 32-bit versions of Office they may have installed before reinstalling Office and updating to the beta version.

In addition to being in the Office Insider program, those who want to test out 64-bit Office on their Arm Windows machine will also have to be running the Windows 11 Insider Preview. There are also a few features that Microsoft mentions haven't come to the Arm version of Office yet, though that’s to be expected given that it’s currently in beta. It is, however, perhaps a little awkward that it took so long for a 64-bit Arm version of Office to come to Windows - M1 Macs got a native version late last year. For those with Arm machines, it’s probably a good sign - having native apps is likely going to be more efficient than emulation, and provide better performance. Unfortunately previous versions of Office (2007 backwards) do not have a data type that holds a 64-bit value, and in 2010 32-bit. Fortunately VBA uses VERY few pointers 95 of them are involved in API or DLL calls.

Its contentious list of supported CPUs includes a handful of Qualcomm chips, and it used the Arm-powered Surface Pro X to show off the tablet capabilities of its new OS. The main difference between 32 and 64-bit Microsoft Office (VBA wise) is that any pointers now need to be 64-bit rather than 32. Microsoft hasn’t shied away from talking about Arm with Windows 11. If you are working with Office 2016, 2013, 2010, and the newer versions, you will be presented with two different Office options: The 64-bit and 32-bit version. In addition to the new design, Office will also adapt to your Windows light / dark mode, so you should be able to avoid the experience of opening a document and having it blast light into your eyes at night. While it uses a similar design to Windows 11, it’ll be available whether you're running the Windows 11 Preview or Windows 10. Microsoft also announced a redesign of Office, which you can see above and below. The new version of Office is currently in beta, available to Office Insiders. Microsoft is announcing that the next version of Office for Windows 11 will have a native 64-bit Arm version, for improved performance on large or picture-filled documents, and support for 64-bit add-ins.
