    Hi,

    VS2022 can add these interfaces, but not 2019

    Glad to know that VS2022 and Microsoft Excel 16.0 Object work for you. For problems about VS2019, I found a fix for add class:https://developercommunity.visualstudio.com/t/MFC-Long-list-of-errors-generated-when/1588036 Please consider using VS2022 instead of VS2019. Best regards, Minxin Yu
