When installing Python 3.5 on Windows (I checked the 64bits installer but I believe the same issue will be with the 32bits), the default installation path when installing for "everyone" is now C:\ Program Files\Python35.

When subsequently installing packages via pip, the installation crashes midway with a cryptic error about "permission denied" (if I remember correctly). I checked with the cryptography module.

It is not an issue with access rights but with the whitespace in "Program Files". Reinstalling Python to C:\Python35 fixes the issue (pip install cryptography runs correctly).

Issues with pip should be reported to its GitHub site. But installing to the "Program Files" directory certainly isn't a problem for pip. You need to run it with administrator rights.
