File I/O Input Output Error during installation

The developers have been made aware of an issue with the “InstallerLauncher” on Mac OS X El Capitan and above and are working on an update.

However, in the meantime, you can access the installer files themselves inside the “Installers” folder that was included in the DMG.

Once inside the Installers folder, choose the package for state you’d like to install.

Please note that depending on your security restrictions, you may need to hold Control and Click on the Installer, then choose “Open” from the pop up menu and then click “Open” again when prompted to install.
