问题
I have tried everything and I have no idea where to go from here. When I call the command pip install python-docx I get this:
running build_ext
building 'lxml.etree' extension
error: Unable to find vcvarsall.bat
----------------------------------------
Command "c:\users\alex\appdata\local\programs\python\python35-32\python.exe -c "import setuptools, tokenize;__file__='C:\\Users\\Alex\\AppData\\Local\\Temp\\pip-build-u2i_l872\\lxml\\setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record C:\Users\Alex\AppData\Local\Temp\pip-26nq6ot7-record\install-record.txt --single-version-externally-managed --compile" failed with error code 1 in C:\Users\Alex\AppData\Local\Temp\pip-build-u2i_l872\lxml
at the end.
I have tried locating vsvarsall.bat and setting the path. I can't seem to find it in C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools and there is no tool folder in C:\Program Files\Microsoft Visual Studio 12.0\Common7. I'm on 64bit Windows 10 and python 3.5.1.

This is a pretty common issue people run into with Python modules. You can read up more on it here
What you can do is install a precompiled version of lxml, which is a module that python-docx relies upon. You can identify this requirement by looking at the error message, or by looking at the python-docx github page here, which lists all requirements for python-docx.
Luckily, Christoph Golke provides some precompiled modules for us, available here. <--- Hotlink that, you'll use it quite often.
Download and install the lxml module first from Christoph Golke, then try rerunning your pip install.

I had the same issue.
After countless tries to install the right Visual C++ compilers and setting the Variables, I got one step further but it still didn't compile. I suggest to follow the other answer's advice and install a precompiled version of lxml. After doing than, I could pip install python-docx without a problem.
Keep in mind that I had to use the WinPython Control Panel to install the downloaded .exe!
More information here: Cannot install lxml on windows, fatal error C1083: Cannot open include file: 'libxml/xmlversion.h'
