PDI 6 does not start

Hi everyone,

I am having trouble to run PDI 6 in my computer. This is what I did.

1. I have downloaded "pdi-ce-6.0.1.0-386" and tried to run it in my laptop. Current OS is Windows 8.1 Pro 64bits (x64).
2. I have downloaded and installed the latest version of Java (1.8.0_66-b18). In my computer Setting it says this is a 32bits version (not sure if this is correct)
3. I tried several times to run spoon bit it did not work
4. I updated the PATH adding the variable %JAVA_HOME%\bin; to the current value. I added a new system variable called CLASSPATH with value %JAVA_HOME%\lib and another one called JAVA_HOME with value C:\Program Files (x86)\Java\jre1.8.0_665. I tried to run spoon and it did not work
6. I have downloaded PDI 5.0.1 and it runs

I cannot understand what I am doing wrong. I could be PDI 6 requires specific settings to be run. Can anyone help me?

Thank you
