Installing boost 1.52 with VS2012

Installing boost 1.52 with VS2012

I followed these instructions to install boost and to compile all libraries:
https://www.quantnet.com/threads/tutorial-quantlib-boost-installation-in-visual-studio-2012.11891/
Boost Installation The Boost library can be downloaded here. Currently,
the latest version available is Boost 1.52.0. You can build boost by
following the instruction here.
Alternative you can download a pre-built lib from here. Once downloaded,
copy the installer into the Boost 1.52.0 folder and run it. Rename the
folder to lib once done.
So I downloaded boost 1.52, then copied that to C:\Program Files (x86)\boost\
I then downloaded the 1.52 64 bit installer and once downloaded, pasted
that to:
C:\Program Files (x86)\boost\boost_1_52_0\boost_1_52_0\
I executed the installer- it said "extracting" and then many library names.
I then renamed the last folder to lib, so that I had:
C:\Program Files (x86)\boost\boost_1_52_0\lib\
In my VS2012 I then added the previous directory to my project. The
project then starting parsing through the libraries and I had no linker
errors. However, when building the project I still got:
LINK: fatal error LNK1104: cannot open file
'libboost_date_time-iw-mt-gd-1_52.lib'
(The only usage of boost in my project is file_mapping and mapped_region)
Help?
