I am trying to use the following code to create an instance of Microsoft Word
and then free it. This code is not working as word is still running after I
close my application. What am i doing wrong?

Type wordApplicationObjectType = Type.GetTypeFromProgID("Word.Application");
object wordApplicationObject =
Activator.CreateInstance(wordApplicationObjectType);
try
{
   //do something
}
finally
{
   Marshal.ReleaseComObject(wordApplicationObject);
}

Thank you
