That is the wrong VS version for python2.7, unless you rebuilt python 2.7 and all \
extensions using VS2015 you might hit bugs because of problems with C RTL cross \
version mixing that does not work in all cases.
This is version you need if you are using binaries from pyton.org \
<http://pyton.org/>: https://www.microsoft.com/en-gb/download/details.aspx?id=44266 \
<https://www.microsoft.com/en-gb/download/details.aspx?id=44266> (google visual \
studio for python)
