Most likely because your Windows is a 32 bit. You will not be able to run 64-bit applications. Minecraft will run just as fine on a 32-bit if you have enough RAM, 64 bit lets you how ever run it with higer graphics.
Any game designed to run on DirectX 11 or higher will run on Windows 8, as well as native Windows 8 apps. Games that are designed to run in, for example, XP or lower, may not run correctly in Windows 8.
