Problemas no arquivo do bastão

Question

Estou tentando configurar um servidor de discórdia e baixei o projeto do Git, mas há um arquivo chamado runbot.bat, que é necessário para ser executado e, quando eu o executo, recebo o erro:

'REG QUERY "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /v HideFileExt 2>nul' is not recognized as an internal or external command, operable program or batch file. =ValueValue was unexpected at this time.

runbot.bat:

@ECHO off

CHCP 65001 > NUL
CD /d "%~dp0"

SETLOCAL ENABLEEXTENSIONS
SET KEY_NAME="HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced"
SET VALUE_NAME=HideFileExt

FOR /F "usebackq tokens=1-3" %%A IN ('REG QUERY %KEY_NAME% /v %VALUE_NAME% 2^>nul') DO (
    SET ValueName=%%A
    SET ValueType=%%B
    SET ValueValue=%%C
)

IF x%ValueValue:0x0=%==x%ValueValue% (
    ECHO Unhiding file extensions...
    START CMD /c REG ADD HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced /v HideFileExt /t REG_DWORD /d 0 /f
)
ENDLOCAL


IF EXIST %SYSTEMROOT%\py.exe (
    CMD /k py.exe -3.5 run.py
    EXIT
)

python --version > NUL 2>&1
IF %ERRORLEVEL% NEQ 0 GOTO nopython

CMD /k python run.py
GOTO end

:nopython
ECHO ERROR: Python has either not been installed or not added to your PATH.
