Biicode 3.3 installer is not working on OS X El Capitan

On OS X El Capitan, here's what I'm getting when trying to install through the installer:

A dialog pops up and says:

This package is incompatible with this version of OS X and may fail to install.

Installing this package may damage your system, and the installation may fail. To stop the program and the installation, click “Cancel Installation”.

If "Install anyway" is chosen, the installer returns an error at the summary step:
