(2) The Java version is too low ，jdk1.6 or above is sufficient，For details, please check the spoon.bat configuration file.

(3) The Java environment configuration is correct，But after double-clicking spoon.bat, it flashes and disappears，Modify the memory configuration in spoon.bat：

if “%PENTAHO_DI_JAVA_OPTIONS%”==”” set PENTAHO_DI_JAVA_OPTIONS=”-Xms2058m” “-Xmx1024m” “-XX:MaxPermSize=256m”

Change for

if “%PENTAHO_DI_JAVA_OPTIONS%”==”” set PENTAHO_DI_JAVA_OPTIONS=”-Xms512m” “-Xmx512m” “-XX:MaxPermSize=256m”
