Installing Theano on Windows 8.1 using Anaconda: setting up the system path configuration script

I am trying to install Theano on windows 8.1 64 with Anaconda following the step by step tutorial provided here: http://theano.readthedocs.org/en/latest/install_windows.html . I am stuck with the environment configuration script 'env.bat' needed to set up the system path. The example is for a WinPython distribution, but as I'm installing in Anaconda and I don't know how to set up this particular line.

This is an example for WinPython:

REM add winpython stuff
CALL %SCISOFT%\WinPython-64bit-2.7.9.4\scripts\env.bat

      

        
        
        
      

    

What directory should I set here after CALL, given that I am using Anaconda? Amazingly many, can anyone help?

EDIT: Note that SCISOFT is the directory where WinPython is installed in the tutorial, the author says "the script assumes you have installed a WinPython distribution, update the winpython line otherwise." and this is what I cannot do because it is not specified what to specify.

I include the whole .bat, although I have no problem with other settings:

REM configuration of paths
set VSFORPYTHON="C:\Program Files (x86)\Common Files\Microsoft\Visual C++ for Python\9.0"
set SCISOFT=%~dp0
REM add tdm gcc stuff
set PATH=%SCISOFT%\TDM-GCC-64\bin;%SCISOFT%\TDM-GCC-64\x86_64-w64mingw32\bin;%PATH%
REM add winpython stuff
CALL %SCISOFT%\WinPython-64bit-2.7.9.4\scripts\env.bat
REM configure path for msvc compilers
REM for a 32 bit installation change this line to
REM CALL %VSFORPYTHON%\vcvarsall.bat
CALL %VSFORPYTHON%\vcvarsall.bat amd64
REM return a shell
cmd.exe /k
