Presets in Photoshop Lightroom trial version

Moving to Lightroom Classic CC — The desktop-focused app

Yes, the trial version is the same program as the full LR-CC version.

I've downloaded multiple presets on the trial version, have watched multiple tutorials and STILL can't use presets, they won't show up. I'm running windows 8, is this the problem? I want to get the full version but need to see if it works ok.
