I've HS3 & 4 running well on my desktop iMac without issues. However, I've tried to install this on my MacBook Pro laptop and cannot get it to run, reporting an error message that Java could not launch it and to check Java console for possible errors. No such errors have been found.
This is extremely frustrating, as i'd like to use it on the laptop when away from home. I have HS3 and 4 on my iPad but prefer to use the laptop.
