Have you tried running the example program excelreportdemo.prj that ships with CVI?  It ends the excel process by discarding multiple handles, and it works even if you're editing a cell or have an Excel dialog open, etc.  Try running this without modification and verify that the excel process is closed when you quit the CVI app.
Here's the Quit function from excelreportdemo.  It checks for and closes handles for the worksheet, chart, workbook, and excel application.
int CVICALLBACK Quit (int panel, int control, int event,
        void *callbackData, int eventData1, int eventData2)
    switch (event)
        case EVENT_COMMIT:
            if (worksheetHandle)
                CA_DiscardObjHandle(worksheetHandle);
            if (chartHandle)
                CA_DiscardObjHandle(chartHandle);
            if (workbookHandle)
                ExcelRpt_WorkbookClose(workbookHandle, 0);
                CA_DiscardObjHandle(workbookHandle);
            if (applicationHandle)
                ExcelRpt_ApplicationQuit(applicationHandle);
                CA_DiscardObjHandle(applicationHandle);
            QuitUserInterface (0);
            break;
    return 0;
