Can not execute an extracted app file

A Mac App, which is distributed through the homepage rather than the Mac App Store, is usually distributed in a DMG or PKG format, but it is often distributed in a ZIP format too. However, sometimes you can not launch the app extracted using Bandizip with the message "Unable to open the app because an unconfirmed developer has deployed it." as shown below.

This problem is caused by a sandbox policy for apps that are registered in Apple's App Store. To solve this problem, right-click and select Open like this.



If you still can't solve the problem, please unzip it with the finder instead.
