Don't Trust MSDN Installer

I think MSDN has been one of the absolutely best things that ever happened to developers, but, by golly, its installers always sucked. The latest ones detect an earlier library and offer a “quick install” option which preserves the options of your current MSDN setup. It lulled me into thinking it’ll just take over the old library and refresh installed content. How surprised do you think I was when I couldn’t look up anything because it wanted the original DVD (which I don’t even have right now)?

By the way, does anybody know how come MSDN doesn’t preserve the language filter anymore? It used to. If I choose to see only C# syntax, why do I have to do it on every single page?
