Configure JAVA_HOME environment variale correct

Hi,

I'm trying to install the biserver-ce-6.1.0.1-196 version.
I'm running Windows 8.1. And I want to run it local.
My assumption is that I don't need requirements like a running Tomcat or MySQL-DB beforehand. Is that right? Cause I didn't find any hint for that. I thought the installation would set up it's own services...
I seem not to configure the environmental variable for JAVA_HOME correctly. Cause when I run the "start-pentaho" batch the shell pops up for just a moment and then it closes. I couldn't make a screen from that (too fast). But I read sth like the environmental variable is not defined correctly.
My JRE-path is C:\Program Files (x86)\Java\jre1.8.0_77
I tried to set the environmental variable "JAVA_HOME" as a system variable with the path "C:\Program Files (x86)\Java\jre1.8.0_77" (without the commentation marks).

So then I tried to start the tomcat from biserver-ce first. Like the wiki said: http://wiki.pentaho.com/display/Serv...indows+service
There was the same problem.

For more information: I only have the JRE 1.8 above (no JDK or sth else)
I looked up the jvm.dll in C:\Program Files (x86)\Java\jre1.8.0_77 and only found client\jvm.dll no server\jvm.dll
(But in the service batch it says it would take either)

So that's why I'm stuck. I probably don't define the environmental variable right...

Pls help!

Thanks in advance.
