CIS virtualization does not work properly

Hi,

I have another problem with CIS Pro. I have win 8.1 64b, latest version CIS. My problem is on the screen. Please have look at the attachment - it is much clear. I have HIPS ON - safe mode, fully virtualization ON and when I launch some file CIS asks me if I want launch this file as ISOLATED. I choose isolated and file is not launched in Sandbox.
