Download via Epic Launcher the current version (either via INSTALL, UPDATE or VERIFY which is dependent on your current ADK version), then download the files from the github & google drive links, as provided by Studio Wildcard at page 1.
When done extract their content to the main folder of your ADK. Make sure you overwrite the correct folders when extracting. When done correctly, startup the batch file “ARKDevKit”, wait for it to load (it can take a while, depending on your PC specs) and voila.
