Requirements:
- A Windows computer
- A Xbox 360
- A USB
- Administrative Permissions on your account
step one: getting horizon
Firstly, go to https://www.wemod.com/horizon and click on "FREE DOWNLOAD". Open the program once its installed, and then open it. It should look like this:
Go ahead and click on the "INSTALL" button. It will require administrative permissions to install. Once its done installing, you can now open up the program. It should be in your Start Menu!
step two (optional): make a wemod account
If you want to use more tools that Horizon uses, you need to make a WeMod account. I will not showcase how to create an account, but if you wish, it's at the top left of the menu bar.
step three: setting up the usb
You now have to make your USB a Xbox360 storage device. Log into your Xbox 360, go to "System", then go to "Storage". If you plugged in your USB, you should see your device on the menu. You must then configure the USB. If you haven't already, when opening the device, you should see a popup stating to 'remove all content on the device and configure it for Xbox 360 storage'. Select Yes and let it set up your USB. There is a video tutorial to configure your device as well:
