Download and install the main file first, this will provide you with the required plugin, meshes and the "default" deep black armor. If you want another color, install that afterwards. If you didn't install it via the Nexus Mod Manager (why wouldn't you though, it's awesome), you might have to activate it in your Skyrim Launcher first. Just click on "Data Files", check "TrissStandalone.esp" and done.<br />

If you had an old version installed, please deinstall it before updating to the new one.
