How can I start MS Office Word from .NET without Add-ins?

Question

I'm using MS Office 2003 PIA to create a MS Word document from c#.

ApplicationClass officeApplication = new ApplicationClass();

Is there any way to specify that I don't want any office add-ins to be loaded using this method?

EDIT:

I know that one can do this via command line so I'm pretty sure there must be a way to do it from code:

"C:\Program Files\Microsoft Office\Office11\Winword.exe" /a  

Answer 1

This code unload the AddIns

officeApplication.AddIns.Unload(false);

Edited:

When you need to mix the process start and possibility to use the office "application" interface, you need the Marshal.GetActiveObject command.
Example :

        //startup without plugins
        System.Diagnostics.Process.Start(
            @"Winword.exe",
            @"/a");
        //give a time for startup
        Thread.Sleep(2000);
        //attach to office
        Application officeApplication = (Application)Marshal.GetActiveObject("Word.Application");

Answer 2

Try this

System.Diagnostics.Process.Start(
  @"C:\Program Files\Microsoft Office\Office11\Winword.exe", 
  @"/a");
