Word automation question

[C++ Programming]

I create an instance of Word by
app.CreateDispatch("Word.Application");


In task manager I can see this has started winword.exe with these command arguments:
WINWORD /Automation -Embedding

But I want it to start with
WINWORD /a /Automation -Embedding

Is there any way to make CreateDispatch start word with: "WINWORD /a /Automation -Embedding" ?
