I am trying to setup ES 5.0 on my machine. ES 2.2.0 was the prev. one which is working fine. Now I am trying to upgrade it. During installation I am receiving this error. Error: encountered environment variables that are no longer supported Use jvm.options or ES\_JAVA\_OPTS to configure the JVM ES\_HEAP\_SIZE=-Xms512m and -Xmx512m: set -Xms-Xms512m and -Xmx512m and -Xmx-Xms51 2m and -Xmx512m in jvm.options or add "-Xms-Xms512m and -Xmx512m -Xmx-Xms512m an d -Xmx512m" to ES\_JAVA\_OPTS What am I missing here ? ---

Have you seen this? [https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking\_50\_packaging.html#\_jvm\_options](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking_50_packaging.html#_jvm_options) ---

the jvm.config file looks OK. Do I need to make any modifications here ? ---

You are probably setting ES\_HEAP\_SIZE somewhere but you should not do it anymore and use ES\_JAVA\_OPTS instead. ---

@dadoonet is correct, but you should prefer `jvm.options` over using an environment variable. Note that your unsupported `ES_HEAP_SIZE` setting is not in the correct format to begin with though. ---

I am not able to figure out where is the ES\_HEAP\_SIZE option set. I tried looking into the Env. Variables, YML Files. But couldnt get any references. Also the jvm.options file also looks clear. These are the steps I have followed inorder to setup ES 5.0. 1. Downloaded the Windows zip - [https://www.elastic.co/v5](https://www.elastic.co/v5) 2. Unzipped the ES folder. 3. Open CMD in Admin mode. 4. Navigated to the ES bin path and execute CMD line - service.bat install ![](https://us1.discourse-cdn.com/elastic/original/2X/6/6cfe62dec94f70ed8b3e9a3d50b9afe76083dd81.png) I am able to load kibana 5 properly. The prb is only with ES. Not getting how and where I need to set these options ? ---

You clearly configured this somewhere, I don't know where. You should start by checking your system environment variables and the service (`service.bat manager`). ---

I tried looking for that variable name but couldnt find it anywhere. Can you please let me know what has changed in the installation process for Kibana between 4.5/5.0 ? ---

you can try to find this variable. just open cmd and paste: set| findstr "HEAP" If you will get the positive result than go to the PC-\>Properties-\>Advanced-\>Environment Variables-\>Scroll down and delete the "ES\_HEAP\_SIZE". ---
