Late comment I suppose, but if you are still having trouble im here to help. Click on whichever one you need to download for your device, and go to finder and go to applications. Open the download once ready, and it should open in your downloads finder. Double click on it, then it will tell you to move applications. Click and hold on the clan gen logo, then drag it to your applications folder wherever. Then once thats done drag it to your app folder thingy / where your backround is. Hope this helps.
