WINDOWS INSTALL
1. Install Python 2.7.13 or higher for Windows. Make sure you add the option "Install for all users" and "Add Python.exe to PATH".

2. Create a directory DOWNLOADS in your python directory (by default c:\Python27\

3. Download from http://www.lfd.uci.edu/~gohlke/pythonlibs/#pipthere
the file
pip-9.0.1-py2.py3-none-any.whl
into the directory DOWNLOADS

4. Press Win key+R

5. Type cmd and press enter.

6. Go to the directory DOWNLOADS where you store the whl file.

7. Write
python.exe pip-9.0.1-py2.py3-none-any.whl/pip install pip-9.0.1-py2.py3-none-any.whl
and press enter

8. Download from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
the library NumPy for cp27 into the directory DOWNLOADS.
You will need to make sure you choose the whl which matches the bitset of your Python (Check this by opening IDLE Python GUI and seeing whether it writes 32 or 64 on top).
I downloaded
numpy-1.11.3+mkl-cp27-cp27m-win32.whl

9. In the command line type
pip install FILEDOWNLOADED
I typed
pip install numpy-1.11.3+mkl-cp27-cp27m-win32.whl

10. Download from http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
the library SciPy for cp27 into the directory DOWNLOADS.
Again, you will need to make sure you choose the whl which matches the bitset of your Python.
I downloaded
scipy-0.18.1-cp27-cp27m-win32.whl

11. In the command line type
pip install FILEDOWNLOADED
I typed
pip install scipy-0.18.1-cp27-cp27m-win32.whl
If it fails, try it again.

12. Download from http://www.lfd.uci.edu/~gohlke/pythonlibs/#sympy
the library SymPy for cp27 into the directory DOWNLOADS.
Again, you will need to make sure you choose the whl which matches the bitset of your Python.
I downloaded
sympy-1.0-py2.py3-none-any.whl

13. In the command line type
pip install FILEDOWNLOADED
I typed
pip install sympy-1.0-py2.py3-none-any.whl

You should be good to go. :-)
