There you have files with the .orc extension. The patch usually adds them, although theoretically it could replace an .exe file or a couple of .dll libraries, but I would only start manipulating them if adding the "Orcs" doesn't help.
So, step 1: get the necessary archives with the updates, i.e., the missing .orc files (ask someone who has these updates installed to send them to you).
Step 2: copy them to your computer.
