I bought Call of Duty 2 today and it is super good, I am trying to install the update. But I a Mac Game newbie and I have no idea how to do it. I have downloaded the file and there is no to tell the installer where COD2 folder is. So I tried installing within the CoD2 folder but no luck it does install but the version number of CoD2 stays the same.

Any ideas what I am doing wrong?
