Windows 10. Download micropolisj package. README says double-click on micropolis.bat. Does nothing.

Oh, maybe I need to install java. Follow link to Java.com, click big "Download Java" button, which takes me to "Version 8 Update 381 (filesize: 62.63 MB) Release date: July 18, 2023". Download, install. Double-click on micropolis.bat. Does nothing.

Decide to open command line, run micropolis bat. Error message:

So Java8 was just updated a few months ago, but this file from 2020 was created with a newer clas??

Where do I find this Java Runtime class version 57? I can't find a download anywhere. How do I install it on Windows 10? ELI5 because I've been using computers for 35 years and I'm completely lost. This is too much work! LOL
