FearLess Cheat Engine

Hello,
I am just trying to install cheat engine on mac, but I keep getting errors. First, I got the installer core error from my antivirus so I disabled it and then uninstalled it temporarily. Now, when I try to install it with no anti-virus it says that the installer is not recognized. Image linked below.

Please Help!
Thanks!

Based on the screen shot, it doesn't look like you clicked the "Download Cheat Engine 6.2 For Mac" link. Are you sure you downloaded the right file?

Yes, I have dowloaded it three times too. It is the dmg file not an exe or rar.
