How to Fix Excel for Mac Run-Time Error 1004 Add-In Name Failed
Question details
Users encounter a Run-time error 1004 related to a failing 'Addin' object whenever they open a workbook in Excel for Mac.
- Product
- Excel
- Device & OS
- Mac
- Scenario
- Opening any workbook, including blank ones, in Excel for Mac.
- Observed behavior
- Excel displays 'Run-time error 1004: Method Name of object Addin failed'. This happens even without VBA code present and is usually caused by an incompatible or faulty add-in.
Save your work and take note of any newly installed software or Excel add-ins (like Adobe Acrobat) that might have triggered this compatibility issue.
Disable Suspected Excel Add-ins
Identify and turn off the problematic add-in from the Tools menu to stop the error from appearing upon startup.
Since this error frequently stems from third-party add-ins trying to load incorrectly when Excel starts, disabling them one by one helps isolate the culprit. The Adobe Acrobat add-in is a common trigger for this specific error on macOS.
Launch Excel for Mac, click on 'Tools' in the top Apple menu bar, and select 'Excel Add-ins' (or 'Add-ins').
Uncheck the boxes next to your active add-ins. If you have the Acrobat PDFMaker or similar third-party add-ins installed, uncheck them first.
Click 'OK' to save your changes. Close Excel completely, and then reopen it or create a blank workbook to see if the Run-time error 1004 is resolved.
Update Microsoft 365 and Third-Party Software
If disabling the add-in works but you still need its features, updating both Excel and the third-party software can resolve underlying compatibility bugs.

Frequently Asked Questions
What does Run-time error 1004 mean in Excel for Mac?
Run-time error 1004 generally indicates a macro or VBA failure. In this specific scenario, it means an installed add-in failed to load its 'Name' property correctly when the Excel application started.
Why does this error occur even when opening a blank workbook?
Excel attempts to load all active global add-ins every time the application launches or a new file is created. If an add-in is corrupted or incompatible, the error will trigger immediately, even on a fresh, blank workbook with no data.
How do I permanently remove a problematic Excel add-in on Mac?
To permanently remove an add-in, navigate to the Excel Add-ins folder on your Mac (typically found under Library > Group Containers > UBF8T346G9.Office > User Content > Add-ins) and move the specific .xlam or .xll file causing the issue to the Trash.
