As you noticed, Visual Studio Express only contains the 32-bit Compiler. You have to download and install the "Windows SDK for Windows 7 and .NET Framework 4" from http://www.microsoft.com/download/en/details.aspx?id=8279to get the 64-bit compiler (this will also install the IA64 cross compiler just in case your keen on a real adventure:)
