The 64-bit compiler is in VC 2008 Express as well, just not exposed in the IDE. I know this because when I got the Absoft Fortran compiler I was told to download VC 2008 Express, because Absoft uses the VC9 linker. And indeed there was a 64-bit compiler in VC 2008 Express as well, just not available from the IDE. If I remeber correctly, some fiddling with vcvars.bat was required to turn it on. I never tried to build Python extensions with it, though. In the beginning I thought Absoft had given me the wrong product, because I had ordered a 64-bit Fortran compiler and I "knew" VC 2008 Express was only 32-bit. But they assured me the 64-bit VC9 compiler was there as well, and indeed it was.
