It's one of a handful of mods you need to manually install the rest can be done by an organiser. Just download it and follow the instructions namely export, drag and drop. You won't notice it, but many mods rely on those new functions to work properly. It basically adds new libraries and methods for mod developers. You're going to want to use OBSE, or Oblivion Script Extender [as well. One of the most common crashes is when you try to launch and the game immediately crashes to desktop this is almost certainly because a mod is loading BEFORE another mod it requires, and therefore can't find the files it needs and crashes the game. It organises your installed mods to load in the "correct" order. LOOT, or the Load Order Optimisation Tool, is another must-have. It's all very technical and case-by-case, so I'd recommend only using it once you see an install call for it to be done. Wrye Bash [is a highly recommended alternate though, and at the very least it can be used to "bash patch", meaning it will take various mods and pseudo-merge them to work nicely together. Newer ones will work, but may cause issues. I'd recommend using this over other mod handlers, simply because it's designed with Oblivion in mind. Here's the best place to start: Download the Oblivion Mod Manager [Using this program, you can load mods into it and then install/uninstall from your game much, MUCH easier.
