Close Photoshop / Illustrator. Creative Cloud running at your computer should install extension automatically if connected to internet after a while. You should be notified about extension installation from Creative Cloud tray. If the waiting is prolonged, then restarting Creative Cloud may help to trigger sync with Adobe Exchange.
After successful install you should see new items available at Window / Extensions / Krasbit Recognition menu of Photoshop / Illustrator
If automated setup via Creative Cloud failed and new items are not available, then download and install .zxp extension manually via ZXPInstaller. See instructions under Download/Install another way link at ADOBE EXCHANGE.
