64位Windows计算机上的32位python

Question

I've downloaded pythonxy (2.7.6.1) on my new 64 bit Windows machine (Windows 7 Enterprise, SP1). When I try to run python, I get an error saying the side-by-side configuration was incorrect. WinPython 32 bit (2.7.6.3) shows the same behavior, WinPython 64 bit is fine.

However, I badly need to compile Python modules with boost and found myself taking the first few steps into what I believe will be searching-the-internet/configuration/compilation hell for 64 bit, so I'd rather try to make the 32-bit python work, for which I have my whole MinGW procedure set up and working. Does anybody know what I need to do in order to fix the side-by-side error? Install some redristributable package or something like that?

Answer 1

From the event log message, it looks like it wants a newer version of the VC90 C-runtime. Two options:

1. The installer may have installed a newer redistributable, but a reboot may still be required to finish the process.

2. Try installing the latest C-runtime distributable yourself: Microsoft Visual C++ 2008 SP1 Redistributable Package (x86) .

Answer 2

I just got an answer from one of my colleagues who told me had the exact same problem. The solution was indeed downloading and installing a version of vcredist_x86.exe, but the trick is to find the exact right one. Apparently you can get to a page somewhere from where you can choose the right version. Sorry for not being able to give more exact information, I just have the file now and it works, but it doesn't even say the version number in the file name. This is all very obscure for my taste, but then I'm not a Windows guy.
