The work required to update your add-ins for 64-bit will vary based on the code.įor example, any use of VBA's DECLARE statement to load external functions in compiled dynamic libraries will require that those libraries support 64-bit. Office add-ins (add-ins using the JavaScript-based APIs) are not impacted by this change.
The primary impact of this change is to compiled add-ins. I develop add-ins or write VBA for Office for Mac. If you use or develop add-ins in Office for Mac, you may need to update those add-ins to 64-bit. If you use Office for Mac but don't use any add-ins, you should be unaffected by this change. What does this change mean for me? Office 2011 On Mac All releases of Office for Mac after Augare 64-bit only. 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.
