I havent tried #4 yet, but I would assume u run the archive.exe with the mentioned options in the command line under the exe properties. I would imagine, it extracts the stock maps, to your steamapps/common/companyofheroes2/coh2/data/scenarios/mp folder...but i havent tried.
Im having trouble with #4 as well, when I run Archive with that command line, nothing seems to happen and nothing has been put into COH2\Data
