问题
I am trying to install biopython to run with Python 3.3 on a Windows7 computer.
I have downloaded the biopython executable biopython-1.61.win32-py3.3-beta.exe. When I attempt to run the executable, however, I get the message "Python version 3.3 is required, which is not found in the registry." Python version 3.3 is present on my computer. I have been running programs through it for a month or two. It was installed from the file python-3.3.0.amd64.msi, and is located in the Program Files (x86) directory.I have tried reinstalling Python 3.3 but get the same error message.
Does anyone know how to get around this problem?
回答1:
Python.org provides Windows installers in two flavours, 32 bit ("win32") and 64 bit ("amd64"). You need matching library installers for your Python version. You are trying to use a 32 bit Biopython installer with a 64 bit Python.
As instructed here http://biopython.org/wiki/Download there are experimental 64 bit Windows installers for Biopython, NumPy, etc here: http://www.lfd.uci.edu/~gohlke/pythonlibs/
Or, you can install the 32-bit version of Python 3.3 for Windows, and then use biopython-1.61.win32-py3.3-beta.exe

You can try to solve this problem by fixing a blank option in the Windows registry. https://stackoverflow.com/a/11507968/3962648 provide details of similar issue when installing numpy. In short, you can just run the windows command line and type in: "reg copy HKEY_LOCAL_MACHINE\SOFTWARE\Python HKLM\SOFTWARE\Wow6432Node\Python /s"
