Blender enables extensibility through the use of plug-ins created in the Python scripting language. Therefore, in order to use the plug-ins required for wonderland content import you'll have to install Python.
IMPORTANT: When you first launch Blender, take a look at the Console Window that opens on your system and take note of the Python version that blender looks for at startup.
You can download and run the Python installer from here... (but DO NOTE THE FOLLOWING IMPORTANT POINTS):
Make sure that the version you install is the same as the version on which Blender was compiled (see the note above to help identify which version you need).
After you install Python:
Make sure to append your python installation directory to your PATH environment variable, and
Add a new environment variable called PYTHONPATH with the value:
[PYTHON_INSTALL_DIR];[PYTHON_INSTALL_DIR]\DLLs;[PYTHON_INSTALL_DIR]\Lib;[PYTHON_INSTALL_DIR]\Lib\lib-tk
(where you must substitute your Python installation path for [PYTHON_INSTALL_DIR]).
At the end of the day you can test your installation by opening your command-line window and running:
> python
If all is will this will pop you into Python command mode. To exit out simply invoke:
>>> exit()
Finally, the next time you launch Blender if you have a looksee at the console window you should see you've made it very happy.
