I can help you! What type of computer are you using to download Clangen? If it's a Chromebook it probably won't work. Secondly, when you do download, you have to extract the .zip file and go into the Clangen folder until you find the Clangen application and click on that to run it. If you have any more questions, feel free to ask me! :)
If you go into settings, it might tell you. That's where you need to go to see if your computer is a 64-bit or 32-bit computer and download the one that it says your computer is. Just click the about one and in device specifications it will say one 64-bit operating system or 32-bit operating system.
