Unzip it onto your desktop. You shall have a Kai engine 7,4-18 folder.

Explore it and cut/paste its path(/home/…).

Run the terminal(App⇒Accessories⇒Terminal) now and enter the following: cd (your path)

Before going any further, close your browser if you want this to run the easiest way as possible. Just memorize the rest, starting from this point.

Enter your password. The engine shall run.

And you are done. Enter your kaiTag and password or configure.
