I got the sane error. The help text gave this: 

The app has been modified or damaged

The app has been modified, and its code does not match the original signed code. The app may be broken or corrupted, or it may have been tampered with. If you think that an app has been damaged or tampered with, you should delete it by dragging it to the Trash.

Some apps and tools, such as AppleScript or JavaScript applications and some legacy tools, modify themselves after signing. These types of apps cannot be opened unless you override the security settings on your Mac. See Open an app by overriding security settings.
