According to the image you sent, you have TeXLive 2015. You can't update 
that any more: TeXLive distributions are “frozen” when a new one is 
released every year. I would advise you to install, if possible, this 
year distribution:

I don't use Windows, but the error I see in the image you sent seems to 
be about the code page you use (cp720). I don't know if it will cause a 
problem with a new TeXLive 2020 installation.

According to the README in

    https://ctan.org/pkg/revtex?lang=en

yes, that will do ---but I can't be sure if revtex 4.2 (2019) will work 
fine under TeXLive 2015.
