I've upgraded my Elasticsearch installation to 5.6 and now I want to install X-pack. But I get this error message.

I'm running Java 1.8\_144, so it should be the latest.
java -version gives:
Java version "1.8.0\_144
Java(TM) SE Runtime Environment (build 1.8.0\_144-b01)
Java Hotspot(TM) 64-bit Server VM (build 25.144-b01, mixed mode)
Running on Win Server 2012.
Please help. Is there a way to see if there are any old versions of Java installed? There aren't much info about this if I google it.

Are you sure that is the JVM that Elasticsearch is using?
Can you paste the logs from when you first start the service to when you get this error?
Also please use code formatting to make things easier to read, the `` button.
