1. First off, extract this anywhere onto your computer. Then open it up and open up ResHacker. Then you will click on File and Open. Go to where your CA Folder is, and double click on your CA Launcher. Once all that is done you'll be given a bunch of bitmap files.
2. The first one is your main CA Launcher skin. Right-click on this and copy it, open up your Paint (no there's no need to download it because Paint comes with EVERY computer) thend click on Edit and paste it. Ok now you will need to shrink the screen (in other words where you make it bigger, smaller...if you don't get that part I'll show an SS later) and make sure it fits whatever you've pasted or else it will not show up.
3. Ok now customize it anyway you want and then once you've done that and are ready to save it, make sure you save it as a .bmp file (24 bitmap to be precise) or else it will NOT work! If you save it as .jpg or anything else then it will not work. After that it will save your original CA launcher so you can actually do this over and over again. You can create your own text and make it say what you want.
