I don't know if you saw my comment earlier in this thread:

This is a straight "pip install numpy" run in a virtualenv on Windows
7 64-bit with MSVC 2010 (full edition) installed. I still don't have
the time to do detailed diagnosis or digging, but if you cannot
generate the same error yourself I can rerun the command and put the
output into a bug report if that helps. (Please provide a link to the
bug tracker, I didn't see it mentioned on www.numpy.org or on the pypi
page for numpy).
