Problem definition
Users on macOS devices that have Acrobat Pro 2020 installed encounter a runtime error when they launch Microsoft® Office 365 or Microsoft® Office 2016 apps.
Solution
Acrobat 2020 typically runs on an X86_64 chipset. However, the macOS M1 device runs Microsoft® Office 365 and Microsoft® Office 2016 apps on the ARM64/Universal chipset.
The error occurs due to incompatibility between the chipset configuration for Acrobat 2020 and ARM-based devices, such as macOS M1.
To resolve the issue, perform the following steps to set Microsoft® Office 365 apps to open using Rosetta mode on your macOS device.
-
-
Find the app for which you want to use Rosetta mode. Ensure that you've quit the app before proceeding.
-
In the context menu of the app, select Get Info.
-
In the dialog, select the Open using Rosetta option and close.
You should now be able to open the Microsoft® Word app using Rosetta mode. The same settings should be applied to other Microsoft® Office 365 apps.
