Can't install Paint.net on Win 10 Pro

[No Alernative]

I just installed Windows 10 Pro on my old Thinkpad T400, in preparation for the Win7 Pro End of Life event.  Anyway, I have always used Paint.net, and since I did a fresh install of Win10, I had to do a fresh install of Paint.net.  Anyway, I downloaded the latest version 4.2.5, and it seemed to go through almost the entire install process, but then at the end, it arbitrarily shut down, and gives the error,

 

"Windows 7 SP1, Windows 8.1, or Windows 10 (Version 1607) is required"

 

Since this is a new install of Win10 Pro, I am kind of confused as to what might be wrong and how to fix it.  I also tried paint.net 4.2.4 and got the same error.  So it is not an isolated glitch.

Please verify you have Windows 10 Version 1607 or newer installed.  If not, you need to run Windows Update.

To elaborate more on what @toe_head2001 said, you may have installed a pre-v1607 version of Windows 10. Let Windows Update do its thing, and you should be good to go.
