Download preparation
This guide should follow Homepage for MS Windows development platform
First: Download these packages, do not unpack them yet.

take the win32 bit versions.
Install python and necessary packages
I recommend to install a python distribution which is packed with several packages already.
Winpython
You could consider winpython, which includes Ipython, numpy, scipy. matplotlib etc.:
Homepage
Make a folder: C:\WinPython27.
Run the downloaded winpython exe file, and extract to: C:\WinPython27.
Open WinPython Control Panel in ex. C:\WinPython27\WinPython-32bit-2.7.x
Drag the 4 above mentioned packakes, into the window, and install the packages.
For a command window, use the WinPython Command Prompt found in C:\WinPython27\WinPython-32bit-2.7.x, which fixes path issues for finding python.
Trick to set variables in cmd
Make a folder own in C:\WinPython27\WinPython-32bit-2.7.x\scripts and
copy C:\WinPython27\WinPython-32bit-2.7.x\scripts\env.bat to C:\WinPython27\WinPython-32bit-2.7.x\scripts\own\pyt32.bat
and copy C:\WinPython27\WinPython-32bit-2.7.x\scripts\cmd.bat to C:\WinPython27\WinPython-32bit-2.7.x\scripts\own\cmdpyt32.bat
Modify pyt32.bat from
set WINPYDIR=%~dp0..\python-2.7.5
to include ..\
set WINPYDIR=%~dp0..\..\python-2.7.5
Modify cmdpyt32.bat from
call %~dp0env.bat
to include ..\
call %~dp0pyt32.bat
Trick to add .bat files to PATH
If you have permission to change the Environment Variables in windows, you can add the pyt32.bat and cmdpyt32.bat to your path.
Right click Computer -> properties -> Advanced system settings -> Environment Variables -> User variables -> Edit: PATH
Add to end of the Variable value:
;C:\WinPython27\WinPython-32bit-2.7.x\scripts\own
In any folder, hold "Shift" and right click, "Open command window here". Write:
pyt32
python
Install Visual Studio Express 2012 for Windows Desktop
See versions of VS 2012 here.
Take 32 bit compiling, since a horrible imprecision bug has been reported for 64 bit building. See bug #20821.
For 32 bit compiling, you will only need, Visual Studio Express for Windows Desktop.
From http://www.microsoft.com/visualstudio/eng/downloads, download and install: Visual Studio 2012 Express for Windows Desktop.
Skip all extra packages install. After install, just exit any program, which opened after install.
Install Subversion checkout of relax
Install a subversion client. For example: http://tortoisesvn.net/
Right click in winpython folder: C:\WinPython27, and select SVN Checkout. Write the path:
svn://svn.gna.org/svn/relax/trunk svn://svn.gna.org/svn/relax/branches/relax_disp
Build relax
Open the WinPython Command Prompt
Navigate to the SVN checked out relax folder.
cd C:\WinPython27\relax_disp scons
Or navigate to C:\WinPython27\relax_disp, hold "Shift" and right click, "Open command window here". Write:
pyt32 scons
Modify pyt32.bat
Modify C:\WinPython27\WinPython-32bit-xxx\scripts\own\pyt32.bat, and add to end of file
set PATH=%PATH%;C:\WinPython27\relax_disp
Test installation, by clicking C:\WinPython27\WinPython-32bit-xxx\scripts\cmd.bat, and write
relax
relax -g
Tip - shortcut to cmd.bat
Make shortcut to C:\WinPython27\WinPython-32bit-xxx\scripts\own\pyt32.bat, and modify the shortcut. Set
Start in: %PWD%
You can now copy this shortcut around, which open a command prompt at the current folder, and set the paths correctly.
Install other software
xmgrace - for the plotting results of NMR-relax
relax produces xmgrace "'.agr" files for plotting. There exist two ports for xmgrace to windows QtGrace and GraceGTK.
Download QtGrace, and unpack to C:\WinPython27\qtgrace_windows_binary.
Then copy C:\WinPython27\qtgrace_windows_binary\bin\qtgrace.exe to C:\WinPython27\qtgrace_windows_binary\bin\xmgrace.exe
Modify C:\WinPython27\WinPython-32bit-xxx\scripts\own\pyt32.bat, and add to end of file
set PATH=%PATH%;C:\WinPython27\qtgrace_windows_binary\bin
Test installation, by clicking C:\WinPython27\WinPython-32bit-xxx\scripts\own\pyt32.bat, and write
xmgrace
which should start xmgrace.
Python editor
A good lightweight editor for windows could Pyscripter
