Jun 04, 2019 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. If the Update option is missing or you're unable to update, try Microsoft Update to install your Office updates through Windows. To download an update manually, see Office Updates. If you would like to update Office but can't open any of your Office apps, try repairing your Office suite: Go to Control Panel Programs Uninstall a program.

Microsoft Office 64 Bit Upgrade For Mac

Applies to:Office for Mac, Office 2019 for Mac, Office 2016 for Mac

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?

Microsoft Office For Mac 64-bit Upgrade

  • 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.

Mac

If you need guidance on making this transition or have additional questions, please let us know by emailing Office64@microsoft.com and we'll be glad to help.
