How do I change scroll direction of a mouse NOT listed under Mice?

I have a new computer (Dell) and have never before had a PC (Macs only). I connected my favorite mouse, a Logitech M325, and it's working in the normal way. But I want to change the scroll direction to Natural Scrolling - what I'm used to. I've followed the directions available online. Under Mice - Hardware in Control Panel, there's just one mouse listed, an HID-Compliant mouse. First, I assumed that was the one I was using, so I changed it. Turns out that applied to the wired mouse that came with the computer and its scroll direction was successfully changed, as I found out when I plugged it back in. So these directions would work with my computer, but my mouse just isn't showing up as an HID-compliant mouse in the Mice area. I think I found it though...listed as a keyboard. And keyboards don't appear to have a path with a numeric string where I could change the digit to reverse scrolling. I'd appreciate any suggestions on how to fix the scrolling - either how to get my mouse to show up in the Control Panel as a mouse, or a work-around. Thanks.

Hi, there's a support group here:
Wireless Mouse M325 - Logitech Support

Do you have a driver installed for your mouse? Normally that would be automatic when you first plugged it in.

Here is the driver: you could try explicitly installing it.
Wireless Mouse M325 - Logitech Support

Thanks! There's no driver - available downloads are SetPoint and Logitech Unifying Software. I previously downloaded the Unifying software which didn't have any effect; now I'll download SetPoint and see if that adds the option I need.

Thanks; yes, those are great directions and did work to change the direction of the wired mouse that came with the computer. But the mouse I'm using doesn't show up as a mouse in the hardware list, so I can't follow the rest of those steps. I need the mouse to appear on the list of mice in order to complete this sequence.
