Can't Install: VPN.pkg Is Damaged

When installing the CU VPN software on a Mac, you see a message saying the VPN.pkg is damaged.

This article applies to: CU VPN

When installing the Macintosh CU VPN client, you receive an error that the vpn.pkg file is damaged.

How to Solve this Problem

The error message is misleading; the installation package is not damaged. However, a security setting on your Mac is preventing the client installation. To solve this problem, change your Security & Privacy Settings to allow apps to be downloaded from anywhere.

To change the setting, select the Apple menu -> System Preferences -> Security & Privacy, then, under Allow apps downloaded from,  select Anywhere.
