Best regard. I would like to know why the Logstash (version 6.1.1) that I have installed locally, does not accept the Java version that is on my computer. After locating in DOS in the directory where I have it installed ("c: \ Elastic Stack \ logstash-6.1.1"), when I give the instruction " **bin \ logstash**" it produces the following error message:

**_Can not find Java 1.5 or higher._**

Also, if located in the directory of your installation I give the instruction " **bin \ logstash -e 'input {stdin {}} output {stdout {}}'**" (to test the installation), it produces the same error message. The same thing happens if I give the instruction " **bin \ logstash -f logstash.conf**".

Previously I have already started both 'Elasticsearch' (version 6.1.0) and 'kibana' (version 6.1.1). I have Windows 7 Home Basic operating system.

The version of Java that I installed is the 8 (Update 151). Although I do not know why when I check it in DOS (with the instruction " **java -version**") it throws the following information:

_ **java version "1.8.0\_151"** _  
_**Java (TM) SE Runtime Environment (build 1.8.0\_151-b12)**_  
_**Java HotSpot (TM) 64-Bit Server VM (build 25,151-b12, mixed mode)**_

It seems as if it were the 1.8; even so, this is still greater than the 1.5 required by the Logstash.

I'm just beginning to know and use these tools. The next thing I have planned to do is install 'Beats' (Filebeats).

Please, have someone tell me what will be happening with the Java version and how to solve the problem.

I am very grateful to you in advance for your collaboration.

Please look at the attached image.
