Reg is not a recognizable command

[Zoulik]

Every time i start up my JPCSP, i get the error that 'reg' is not a recognizable command, and that i need to download a new version of java. I just downloaded java 7 update 15, the most recent java, and it still wont work.

Can you add a directly check
C:\Progra~1\Java\jre7\bin\Java.exe ?
My freind also have this probrem.

Would this updated start-windows-x86.bat fix the issue?

Code:

@echo off
rem CD to the path of the command line, this is required when running as an administrator
cd /D "%~dp0"

set PATH=%PATH%;lib\;lib\windows-x86\

if NOT EXIST "%SystemRoot%\SysWOW64" goto JAVA32
set key=HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Java Runtime Environment
goto JAVA

:JAVA32
set key=HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment

:JAVA
set JAVA_CMD=%ProgramFiles%\Java\jre7\bin\java.exe
if not exist "%JAVA_CMD%" set JAVA_CMD=java.exe

rem Checking if the "reg" command is available
reg /? >NUL 2>NUL
if ERRORLEVEL 1 goto RUN

set JAVA_VERSION=
set JAVA_HOME=

for /f "tokens=2* skip=2" %%a in ('reg query "%key%\%JAVA_VERSION%" /v JavaHome') do set JAVA_HOME=%%b

set JAVA_CMD=%JAVA_HOME%\bin\java.exe
if not exist "%JAVA_CMD%" goto JAVAMISSING

goto END
