so, it depends on what type of computer you have got. If you've got a microsoft, there should be a symbol for it. The same goes for these types of devices: apple, and the penguin symbol, whatever that is. Then, you extract all files, and then find a file called Clangen, or Clangen.exe. Keep in mind that the app is only for pc for downloading, though there is an online version that worked for my samsung tablet, and i think that it works for any other mobile too.
