  • Hello,

    There are a lot of reasons why add-ins are not loaded by the host application.

    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 a 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.

    Also you may enable your VSTO log file by adding the following on your system environment variables:

    NAME: VSTO_LOGALERTS
    VALUE: 1

    There might be an exception error that is why your add-in is not loading.

    You can check this source for more info on VSTO logging and alerts, but in essence you change two environment variable values depending on what you need to do:

    Displaying VSTO Alert Prompts

    To display each error in a message box, set the VSTO_SUPPRESSDISPLAYALERTS variable to 0 (zero). You can suppress the messages by setting the variable to 1 (one).

    Logging VSTO Alerts to a Log file

    To write the errors to a log file, set the VSTO_LOGALERTS variable to 1 (one).

    Visual Studio Tools for Office creates the log file in the folder that contains the application manifest. The default name is .manifest.log. To stop logging errors, set the variable to 0 (zero).
