The new Sikuli version used by TagUI v5.0 runs on 64-bit systems only, improve verbiage -

>SikuliX is a Java application, that works on Windows XP+, Mac 10.6+ and most Linux/Unix systems (with 1.1.4+ only 64-Bit systems). For Windows, Mac it is complete and should normally work out of the box. For Linux/Unix systems there are a few prerequisites to be setup.

 ### VISUAL AUTOMATION
-TagUI has built-in integration with [SikuliX (base on OpenCV)](http://sikulix.com) to allow visually identifying the web elements and desktop UI (user interface) elements for interaction by providing their images or (x,y) coordinates. Applicable steps are click, hover, type, select, read, show, save, snap, keyboard, mouse. To use visual automation, Java v8 or greater is required.
