Put the cursor at the end of the line, insert the character ";" and complete with the Python path. Do the same to JAVA.

How to test the requirements are correctly installed
====================================================

Make sure that this procedure was done correctly using a **NEW** window of DOS terminal. Do not use any which is already open. 
Open a **NEW** window of DOS terminal and type:

.. code-block:: text
 
 	python -V

Expected:

.. image:: img/howtoinstall_path_conferir-python.jpg


Then check Pillow:

Continue in the DOS terminal or Open a **NEW** window and type:


.. code-block:: text
 
 	python
 	import PIL
 	exit()
 	


Expected:


.. code-block:: text

	Python 2.7.8 (default, Jun 30 2014, 16:03:49) [MSC v.1500 32 bit (Intel)] on win32
	Type "help", "copyright", "credits" or "license" for more information.
	>>> import PIL
	>>> exit()


If you have a message similar to:

.. code-block:: text

	Traceback (most recent call last):
	  File "<stdin>", line 1, in <module>
	ImportError: No module named PIL
	
Install Pillow. If you have Python 32bits, Pillow must be 32 bits too. If you have Python 64 bits, use Pillow 64 bits.


Then check Java:

.. code-block:: text

	java -version

Expected:

.. image:: img/howtoinstall_path_conferir-java.jpg


With Java and Python installed and added to Path, the Markup program is almost ready for use.
