My Boom Drum Machine Virtual Instrument isn't in my plug-ins

I was looking for a plug-in to use to make a simple beat in my Pro Tools Express 10.3.4(I'm aware it isn't the most updated version), and I was looking for the Boom virtual drum machine-which I know I should have, but the only plugins under instruments were: Xpand2, Structure Free, Click. How do I get the Boom virtual drum machine?

All help is appreciated :-)
