simple step by step guide to multitrack recording?

Can anyone describe a simple step by step guide to capturing four channel simultaneously?

Behringer UMC404HD into a Win7 machine.

Drivers working etc. It sees the interface, connects…sound capturing…but…

It only offers me…channels 1-2 or 3-4…
How do I get it to configure for four at once???

Yes I read the manual and reference to multi track but it describes it but does not explain how to…

that’s the frustration.
Or should I look at other software? I have worked with Audacity for basic stereo but I am trying to raise my game.

Have you tried changing the “host” in the Device Toolbar?
Do any of the “host” options provide more than 2 channels?
