oh, you want to know what you need to do.. right..
first read how to use PATH in windows: http://www.java.com/en/download/help/path.xml

then add 2 full paths there:
1) openssl installation directory (example c:\program files\openssl)
2) directory where lua.exe is installed (example: c:\data\lua)

now, open cmd as administrator and get to c:\program files (x86)\rovio\AngryBirds\data\levels\pack1\
you can now use the guide that I posted earlier.
