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

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

From stackoverflow

• Try this

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

  Andrew Jackson : Thanks, but I specifically want to use the PIA as above.

• 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");
  

  Andrew Jackson : Is there a way to stop them loading in the first place? I'm trying to avoid the startup performance hit when customers have lots of add-ins. I need to start word quickly, do some processing and close it again.

  Avram : @Andrew ,see at my update.

  Andrew Jackson : Ah, Thank you. Thats what I am looking for!
