I *strongly* suggest that you update to 2.7.9.

When I have used that site (most recently last July), I have directly 
downloaded and unzipped files.  I see that nearly all .zips have
since been replaced with .whl wheels.

With 64 bit python, you must use 64 bit binaries.  If so, search 
"side-by-side configuration is incorrect" (Google, etc).

I see 'cgohlke', who I presume is the C. Gohlke who made the 
PythonMagick binary, has already given you his best guess.
