Hi, Sorry for all the hassles! Normally you don't need the Microsoft compiler to use relax as the C modules are pre-compiled for 32-bit Python systems (http://www.nmr-relax.com/download.html#MS_Windows). It's only relax developers who need to use this. Sometimes users will install non-supported software (64-bit Python, non-official Python, etc.) and then they may require it. But I can only support one official Python release, currently only 2.7, for the MS Windows distribution archive.
Once the relax_disp branch supports more models, then it will be merged back into the relax trunk and probably released as relax 3.1. Though first relax 3.0 will need to be released. It may take a while for relax 3.1 to come out with full support for relaxation dispersion analyses, and hence pre-compiled modules. As for the errors with 64-bit WinPython, it is probably safe to assume that they have jumped the gun and bundled 64-bit Numpy for Windows before it is ready to be shipped to users. What is strange is that on my Linux test system, I have self compiled 64-bit Python+numpy+scipy+wxPython and I don't have any precision issues. There is something fishy with this WinPython 2.7.5 version.
