GAC: Global Assembly Cache

Using NSIS, I'm writing an installer for a .Net based application along with third party software that the application depends on. We're going to registering some managed .Net .dll's into the GAC (or the Global Assembly Cache).

Since I've never done this before I did a little bit of research. Suffice it to say Wikipedia was a more helpful resource than Microsoft's Knowledge base in getting started.
