Basically, I copied my friend's installation of Medieval 2 Total War because the CD I got was a DVD-rom and I don't have a DVD-player on my computer.

I'm trying to install patch 1.1 but it's not detecting my MTW2 because, most probably, there's no system registry entry for it.

Can anyone help me out here? Is there any way in which I can manually apply the patch?

Thanks in advance.
