We are using DSO Framer(source code provided by Microsoft) to display/edit excel file in our product. The excel ActiveX control is embedded in a control in a windows form. After applying the latest windows update(KB5005698, KB4598243), an excel file can't be opened embedded in the control. The file is opened in an individual window. I debugged the code, the following code
hr = m_pole->DoVerb(OLEIVERB_INPLACEACTIVATE, NULL, (IOleClientSite*)&m_xOleClientSite, (UINT)-1, m_hwnd, &rcView);
return the error 262528.
Can anyone help on this issue?

    According to what you said, you may send feedback to Microsoft with the Feedback Hub app about the update(KB5005698, KB4598243) issue. Or you can contact office team for this behavior.
