I have been trying to setup elasticsearch in windows7 machine by following [https://www.elastic.co/guide/en/elasticsearch/reference/current/\_installation.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/_installation.html) I was able to download, unzip but when running ./elasticsearch, I get the below error, Error: Could not find or load main class org.elasticsearch.tools.JavaVersionChecker Elasticsearch requires at least Java 8 but your Java version from C:\Program Files\Java\jdk1.8.0\_131/bin/java does not meet this requirement I have verified Java versions installed and they look fine, $ java -version java version "1.8.0\_131" Java(TM) SE Runtime Environment (build 1.8.0\_131-b11) Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode) $ javac -version javac 1.8.0\_131 Can someone point out where I am wrong ? ---

I have seen similar things in the past when the JAVA\_HOME contains spaces in dir name. May be try to copy your jdk in another location like c:/java ? But may be this is something else here ---

I'm also having the same problem on a Linux machine. > $ ./elasticsearch > Elasticsearch requires at least Java 8 but your java version from /path/to/java does not meet this requirement > $ java -version > java version "1.8.0\_74" > Java(TM) SE Runtime Environment (build 1.8.0\_74-b02) > Java HotSpot(TM) 64-Bit Server VM (build 25.74-b02, mixed mode) There's no space in my JAVA\_HOME dir name ---

Can you upgrade your jvm to 1.8.0\_131 ---

I've restrictions and am not allow to upgrade my JVM, however I've JVM 1.8.0\_131 in another directory to use. Is there a way to config elasticsearch to point to my 1.8.0\_131 JVM directory instead of going to my default? ---

I guess that changing JAVA\_HOME should work ---
