Is there a simple way to compile a 64 bit app with the 32-bit edition of Visual C++ 2010 Express? What configurations, if any, are necessary?

These steps have worked for me, anyway. Some more details on step 2 can be found in a reference from Microsoft that a previous poster mentioned: http://msdn.microsoft.com/en-us/library/9yb4317s.aspx.
64-bit tools are not available on Visual C++ Express by default. To enable 64-bit tools on Visual C++ Express, install the Windows Software Development Kit (SDK) in addition to Visual C++ Express. Otherwise, an error occurs when you attempt to configure a project to target a 64-bit platform using Visual C++ Express.
