In case of questions

1. Please copy and paste the error message when you email me the questions.
2. You can also capture the screen that shows your problem during installation. Try using Snagit for screen capture.
3. In some cases on Windows, the following command

<syntaxhighlight lang="DOS" style="border:3px dashed black"> python setup.py install </syntaxhighlight> or <syntaxhighlight lang="DOS" style="border:3px dashed black"> pip install <package> </syntaxhighlight> may require the Microsoft Visual C++ compiler for Python 27 to work. You can download this compiler from here.
