  • Hello Julio,

    Office COM add-ins work just fine on Windows 10.

    > My Addin does not work in Windows 10.

    Could you please be more specific? Did you have a chance to check out the COM add-ins list? Is it listed there?

    How do you deploy the add-in on Windows 10 machines?

    First of all, make sure the required windows registry keys were added correctly. See Registry Entries for VSTO Add-ins for more information.

    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.

    Do you get any UI errors?

    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.

    As you may see there can be multiple reasons why you don't see your add-in working on Windows 10 machines.
