This is given free (though requires registration). I found that the package is portable. However, the .exe file is 3 layers deep. Not sure how to make it portable. Tried copying the .exe and then copying the full folder to 1st level sub-dir after portableapps, but this did not work. Tried also to create shortcut in the 1st sub-dir level, but the portableapps suite does not pickup shortcut file.
