Microsoft today announced the public availability of the first 64-bit version of Office that runs on Windows on ARM. Yes, you read that right: It’s ARM64 native and it uses WOA’s emulation to run Office add-ins.
“This new version of Office is designed specifically for the next version of Windows on ARM,” Microsoft’s Mike Smith writes, alluding to Windows 11. “It has been recompiled for the ARM architecture to run fast, bring greater memory availability, offer better support large documents, and maintain compatibility with existing 64-bit add-ins using the new x64 emulation capability provided by Windows.”
To try out this product today, you need a supported Windows on ARM PC, which is all of them, and it needs to be rolled in the Dev Channel of the Windows Insider Preview program, which will give it access to today’s Windows 11 build. If you’re already using a 32-bit version of Microsoft Office (emulated), you will need to uninstall that first. Then, reinstall Office from office.com, join the Office Insider program, and update to the current Beta channel build.
The Office applications that currently run natively as ARM64 include Excel, OneNote, Outlook, PowerPoint, and Word. Other Office applications will still run in x64 emulation mode.
