title: Can't install traits on windows, python
body: <p><strong>Windows 10 64bit</strong></p>
  
  <p>I installed traitsui successfully by pip in python3.52</p>
  
  <p>Qt4 must be installed to display GUI on windows, But the highest version of python Qt4 support is python3.4</p>
  
  <p>So, I install python3.4, when I try to install traits by pip</p>
  
  <p>I got error message:</p>
  
  <pre><code>error: Microsoft Visual C++ 10.0 is required (Unable to find vcvarsall.bat)
  </code></pre>

  <p>I search the error message, get some results, But none of them solve the problem, So I install <strong>mingw</strong></p>
  
  <p>use pip to install traits again, get another error</p>
  
  <pre><code>collect2.exe: error: ld returned 1 exit status
  error: command 'D:\\Program Files\\mingw-w64\\x86_64-5.3.0-win32-seh-rt_v4-rev0\\mingw64\\bin\\gcc.exe' failed with exit status 1

  <p>Is there a way to install traits on windows in python 3.4?</p>
