To fix this issue you will need to disable Gatekeeper. To do this, click the Apple logo on the top toolbar and select System Preferences. Now select Security. If the padlock in the bottom left corner of this screen is not open, click on it. You will now see 3 options for downloaded applications, they are: Mac Store, Mac Store and identified developers, and Anywhere. Please select Anywhere and then confirm your selection. Once this is done, please attempt to download the installer from our website. You should no longer see the damaged file messaging.
