I read about this editor in PC Magazine and decided to try it. I've used Premiere Pro which is too expensive and Cyberlink's Power Director, which is ok but I was wondering if I would like the workflow in this editor, but I have to get it on my computer first and therein lies the rub.

I am baffled by the download options! I am running Windows 10 on my computer.

How are the 3 Cross distribution packages different and which one of them is right for my computer?

I looked at Flatpak and found more confusing options. I tried "Install" but that doesn't appear to be an exe file so I got an error when I clicked the file, something about no associated app.

Download options of what? Sorry, but your post makes no sense, what product are you talking about, what Plasma version, which distribution?
