I have jdk 1.8 installed in my Windows 10 machine.
Downloaded from pdi-ce-188.8.131.52-28.zip, extracted the .zip file & clicked on spoon.bat file but the PDI is not opening neither i can see any error message.
You may need to add a system variable called PENTAHO_JAVA_HOME that points at your java install. Please Google it as I can't give you a link right now.
Thanks Diego its working now.
