Installation problem on Mountain Lion: "Accubarcode Pro (Plus) Installer" is damaged

his is an issue introduced by the default security settings of Mac OS X 10.8 (Mountain Lion), which allow only applications downloaded from "Mac App Store and identified developers". The alert is highly misleading.

Solution 1:

Change the setting in the "Security & Privacy" preferences (Apple menu > "System Preferences..." > "Personal" section > "Security & Privacy" > "General" pane) to "Anywhere", you should be able to run AccuBarcode Pro Installer and get the software installed on your Mac without any problems.

This affects your general settings. If you feel that your "Security & Privacy" should be set back, do this after the installation.

Solution 2:

You can also right-click on (or hold the Control key and click on) Accubarcode Pro Installer and choose "Open" from the popup menu, that will bypass the Mountain Lion app source security policy and execute it normally.

The app Accubarcode Pro Installer will be stored as an exception to your security settings, and you will be able to open it in the future by double-clicking it. This doesn't override your general settings.
