Some third-party Excel com AddIns sometimes block my function: workbook.SaveAs(....), i.e.InvokeHelper(0x785).
When I disable Excel com AddIns from UI (sometimes requies me to run as administrator), SaveAs works well.
So I am thinking whether it is possible for me to disable/enable third-party COM addIns programmatically or CreateDispatch("Excel.Application") in safe mode (just like pressing key ctrl when starting excel).
Thanks.
