I followed the instructions step for step
Download the Source Tools. Don’t unzip.
In Blender:
[LIST=1]Select File > User Preferences
Move to the Addons tab
Click Install From File… in the bottom of the window
Find the downloaded zip file
Find and check the Source Tools’ box. Wait a moment for activation to complete.
Click Save User Settings.
