Word Add-in not showing up? RRS feed

  • Question

  • I was working with a customer today and saw something that I'd never seen before. We installed a word add-in and it did not show up at all on Word. Add/remove programs shows it installed. Word Options > Add-ins > COM Add-ins (where it usually is) did not show it at all. Odd.

    This is a windows vm running within a MAC. (Shouldn't have anything to do with that but I thought I'd mention it too)

    Has anyone experienced something similar?

    According to your description, I suggest that you could check the LoadBehavior of the add-in in registry, it should be set to 3, or you could install your Word Add-in on Windows system to check whether can reproduce this issue.

  • Hello,

    There are plenty reasons why your add-in is not shown in Word. Let me name a few:

    1. By default, if an VSTO Add-in attempts to manipulate the Microsoft Office user interface (UI) and fails, no error message is displayed. However, you can configure Microsoft Office applications to display messages for errors that relate to the UI. You can use these messages to help determine why a custom Ribbon does not appear, or why a Ribbon appears but no controls appear. Read more about that in the How to: Show Add-in User Interface Errors article.

    2. Microsoft Office applications can disable VSTO Add-ins that behave unexpectedly. If an application does not load your VSTO Add-in, the application might have hard disabled or soft disabled your VSTO Add-in.

    Hard disabling can occur when an VSTO Add-in causes the application to close unexpectedly. It might also occur on your development computer if you stop the debugger while the Startup event handler in your VSTO Add-in is executing.

    Soft disabling can occur when a VSTO Add-in produces an error that does not cause the application to unexpectedly close. For example, an application might soft disable a VSTO Add-in if it throws an unhandled exception while the Startup event handler is executing.

    When you re-enable a soft-disabled VSTO Add-in, the application immediately attempts to load the VSTO Add-in. If the problem that initially caused the application to soft disable the VSTO Add-in has not been fixed, the application will soft disable the VSTO Add-in again. Read more about that in the How to: Re-enable a VSTO Add-in That Has Been Disabled article.

    3. Macro security settings are applied to COM add-ins as well.

    Finally, you may find the Troubleshooting COM Add-In load failures article helpful.
