Neither this installer, nor any other, installs absolutely every LaTeX file someone might want to use with LyX. It's the job of your LaTeX installation to deal with that. In your case, that's apparently MikTeX, and my understanding was that it should install the LaTeX files you need on the fly. If it's not doing so, I'd investigate it.
Richard's correct. Go to your Start menu, in the MiKTeX 2.7 group, and run the application named "Settings". In the "Package installation" section of the "General" tab, set the on-the-fly option to either "Yes" or, if you don't mind being nagged, "Ask me first" (my preferred choice). Note that you'll need to be connected to the Internet when you are using LaTeX.
If you prefer (or if you don't normally have an Internet connection available), you can use the "Browse Packages" application to install a bunch of needed packages at one time.
If this doesn't solve the problem, then let us know what fails when you try to install a package.
