So im trying to install the NAM mod but need the 638 update, i download the update and put the updater in the SC4 folder and i open it and it shows "Missing or Invalid Registry/INI Entry", then i press ok, it "updates" and it says its done, but really i check the files it didn't even change/update , help?
You will find the update in Official Maxis Files (http://sc4devotion.com/forums/index.php?page=6) in the menu on your left hand side.
Are you by chance trying to run a No CD crack? That would explain the missing registry entry error and the NAM installer's behavior. There is no way to install the NAM properly without a legitimate, retail copy of the game (with the exception of retail copies purchased from Origin (http://sc4devotion.com/forums/index.php?topic=17693.0), which are unpatched and unpatchable).
