Thx for your reply. As you can see from this pic below:
Btw, I noticed usually EIS will remove 'interactive group' from Chrome and created a new Chrome desktop shortcut without the 'interactive group'. I assume this is for the security reason. But if you know more info regarding this behavior, please explain to me, thanks a lot! Also, I think that`s probably why Chrome 56 lost its icon, not sure about this.
