Microsoft Word For Mac 64 Bit
Start quickly with the most recent versions of Word, Excel, PowerPoint, Outlook, OneNote and OneDrive —combining the familiarity of Office and the unique Mac features you love. Select the language and bit-version you want (PC users can choose between 32-bit and 64-bit), and then click Install. See Steps 2 and 3 on the PC or Mac tabs above to help you with the rest of the install process.
- Download and install or reinstall Microsoft 365 or Office 2019 on a PC or Mac. The 64-bit version is installed by default unless Office detects you already have a 32-bit version of Office (or a stand-alone Office app such as Project or Visio) installed. In this case, the 32-bit.
- Microsoft Office 2016 for Mac was originally released as a 32-bit application. On August 18, 2016 Microsoft released an update that changed every Mac installation from 32-bit to 64-bit. Unlike Office for Windows, Office for Mac is no longer available as 32-bit.

Apple has long encouraged application developers to adopt the 64-bit runtime environment, and we've been hearing from customers that 64-bit versions of Office for Mac are desirable to enable larger address spaces, better performance, and new innovative features. All releases of Office for Mac after August 22, 2016 are 64-bit only.
What does this change mean for me?
If you use Office for Mac but don't use any add-ins, you should be unaffected by this change.
If you use or develop add-ins in Office for Mac, you may need to update those add-ins to 64-bit.
I develop add-ins or write VBA for Office for Mac. What do I need to know?
The primary impact of this change is to compiled add-ins. Office add-ins (add-ins using the JavaScript-based APIs) are not impacted by this change.
The work required to update your add-ins for 64-bit will vary based on the code.
For example, any use of VBA's DECLARE statement to load external functions in compiled dynamic libraries will require that those libraries support 64-bit. The VBA code itself will continue to work as VBA is transitioned to 64-bit, but you'll need to update the external libraries.
