[Biopython] Windows 7 installation issue

[Christoph Gohlke]

Could it be that you are trying to install a 32 bit version of BioPython
on a 64 bit Python installation or vice versa?.

If you are sure your Python version is 32 bit, you can open
biopython-1.53.win32-py2.6.exe, which is a executable zip file, with a
decent archive program, e.g. WinRAR, and copy the content of the PLALIB
directory to your Python26\Lib\site-packages folder.
