The thing that you can download from Microsoft's site seems to include 2.0 and SP2. It installed on its own after uninstalling plain-flavor 2.0. I've got more machines to run this on, so I can doublecheck.

I didn't even think about installing it through Windows Update. I forgot that there are optional packages available through there. However, I'm trying to automate some software installations, and Windows Update isn't exactly conducive to that.
