can you use cygwin to do that?
open up cygwin terminal and type:
./snappy-conf C:\Users\FALAH FAKHRI\Anaconda2\bin\python
when you type the above command make sure you are in the right folder (snap/bin)
if this does not work, another alternative might be the following:
- download and install MinGW (http://www.mingw.org/). check instructions here
