The first zip unzips the other ones, if they are together in one folder and their names are the same except for the part number. I'm not clear what you're saying-it sounds like you're trying to open the further files yourself. I need to get from the zip into the game. when I right click the first file and say 'extract here,' it works, but the following files only give me duplicates. I have the zips saved in a desktop folder. I'm trying to install a fixed version of Appaloosa Plains.
