Install Scala3 using Coursier fails Windows 10

Question
1

Outcome…

(lots of text first)
Wrote scala3-compiler
Warning: C:\Users\stl\AppData\Local\Coursier\data\bin is not in your PATH

Sort of a bad first impression, I think. Tried using cmd as admin and normally. Same result.
Running “scala3” command then failed.

Added the missing path to PATH manually, now giving this result:
C:\Users\stl>path
PATH=C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0;C:\Windows\System32\OpenSSH;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;C:\Users\stl\AppData\Local\Microsoft\WindowsApps;C:\Users\stl\AppData\Local\Coursier\data\bin;

C:\Users\stl>scala3
‘""’ is not recognized as an internal or external command,
operable program or batch file.

That’s where the first hour of my installation process went. Any idea what to do next?

Hi.

Seems like you don’t have a JRE installed.

Running cs java-home should list your current JRE, if installed, or install the default JRE.

Then, ensure to set JAVA_HOME variable to the path output by the cs java_home command.
