Workaround:

1. Open Gatekeeper settings located in "System Preferences > Security & Privacy"
2. Set "Allow applications downloaded from:" to "Anywhere" and confirm by 
pressing "Allow From Anywhere"
3. Download, unpack and run Vizzy
4. Once it is successfully launched, it no longer goes through Gatekeeper. Thus 
you can restore Gatekeeper settings to the default option "Mac App Store and 
identified developers" after successfully launching Vizzy the first time
