Hi, FWIW: I have built rpy2 for 32 and 64 bit Python several times in the past with Visual Studio and Intel ICL compilers. Compiling and linking was not a problem. However, none of those builds were stable and would crash on import. The problem was that R and Python use different, incompatible C runtime libraries; IIRC R tried to release memory allocated by Python/rpy2 or vice versa. The same problem also occurred with the R/tests/Embedding example so it does not seem to be rpy2 specific. Maybe things have changed since.
