Installation script not working on Windows

[Trayani]

Hello, I wanted to check out this engine so I followed the online instructions to install it. But the script always fails.

C:\Users\MyUser\Downloads>install-korge-forge.cmd
KorGE Forge Installer v2024.2.0.2-patch1
Downloading https://github.com/korlibs/universal-jre/releases/download/0.0.1/xzdec.exe into C:\Users\MyUser\.korge\xzdec.exe
The syntax of the command is incorrect.

I tinkered a bit with the script. It seems that the syntax error is coming from this part ↓↓↓.

    IF /i "%DOWNLOAD_SHA256%" == "%EXPECTED_SHA256%" (
        MOVE "%LOCAL_PATH%.tmp" "%LOCAL_PATH%" > NUL 2> NUL
    ) ELSE (
        ECHO ERROR downloading %URL%, SHA256=%DOWNLOAD_SHA256%, but expected SHA256=%EXPECTED_SHA256%
        EXIT /B -1
    )

Once I removed, it, the script returned more output

C:\Users\MyUser\Downloads>install-korge-forge.cmd

The system cannot find the file specified.

Obviously, I will not try to use the downloaded files since authenticity was not verified. But it prevents me from using the engine, hence the issue :)
