Start your PC in safe mode. To do this, reboot it, and start pressing F8 frantically until you're given a list of options for how you want to start windows. Select 'safe mode' and it'll boot up and look really ugly, don't worry it's meant to. Anyway if you're given the login screen, you should be able to click on Admin, if you're skipped past the login screen we'll have to assume you Are admin, in which case just copy paste do whatever you need to do with the file, it shouldn't stop you.
I installed the patch by downloading the new autoupdate, put that in my C:\Program Files\Microsoft Games\Halo\ and then I just double-clicked to run it, and it updated on it's own. Note that when you put that file in your Halo directory, click Yes to overwrite the old autoupdate.
