Blocking Alerts Display in Excel COM

I solved a problem that blocked me from automation my every day processes.

The reason for blocking was that I have MS Excel 2003 installed on my computer, when trying to open a XLSM file constructed in 2007. I have installed a Converter that enables me to open XLSM files but then a nasty window pops up and stalls the whole process (it awaits to be clicked or Enter to be pressed).

In VBA there is a simple solution to the problem:

Application.DispalyAlerts = False

And its counterparty in matlab script is:

hExcel = actxserver('Excel.Application');

set(hExcel, 'DisplayAlerts', 0);
