i trying install python 2.7 , usual libs.

python 2.7 installed (and shell seems ok) - config : win8.1 64bits

setuptools, pip , virtualenv installed after that

microsoft visual c++ 2008 redistribuable installed (to fix [vcvarsall.bat] error), , unistalled basic 2010 visual studio.

when try install libs these popup errors:

  • installation on virtual env = msvcr100.dll missing

  • installation without env = python27.dll missing
