@duntcare yes

I downloaded the Stockfish13 for 64-bit and found that Windows blocked the run when the downloaded files were unzipped. Was it just because I downloaded the wrong program??

I just did some research on my own laptop and it seems that I've got a low-end CPU Celeron CPU and probably isn't supportive to the Stockfish environment requirements. Too bad. I have found a Stockfish 8 program in the Windows Store - a free download (PGN Chess Book). I analyzed one of my earlier games both on the chess.com and the PGN program. They both gave close to the same results. A couple moves in the program were included in the PGN program that were overlooked (both analyses down at the quickest times). But I attribute that to the earlier Stockfish version. Still, it was interesting to compare and combine analysis'. The PGN program also allows comments including the insertion of other lines (those I found on the chess.com engine). I'm in the dark ages, I guess, but no matter how I look at it, any professional analysis is going to do well to helping me improve my game.

Try the .exe for "modern computer", not BM2 or AVX2 that are for more

recent computers

I tried the download which reveals "modern" but my laptop throws up a tab stating Windows has protected my PC and that the Stockfish exe. program might put my PC at risk. Then offers me to run it anyway or don't run it. Am leary of trying it so soon after its release. I'll wait till I hear more from others. The program's credentials may not yet have made it to the general Windows public PC environs.

Ok Is the  new silly protection of Windows or Chrome Absolutely.no risk of virus on Stockfish

Stockfish is a free chess engine, and it is safe. My AntiVirus Protection also ask run it anyway or don't run it, and I just simply press run it anyway and nothing happens.

Add an exception to your antivirus, as you say, it is safe.

Why download anything. You got Stockfish 13 NNUE for free on lichess.org?

so you can use it offline

yep

What's its elo compared to the other version?

Elo= rating, Do you mean SF 13 vs older version? (like 12,11,10 etc)

New stockfish rating vs. the stockfish before's rating.

get this link http://www.computerchess.org.uk/ccrl/404/ and see what's the elo.

FF2 is obviously strong.  Stockfish has 30 incredible programmers to improve it everyday, but  if they continue to copy only the source code, it  will be no much better FOREVER  :-)
