Hello,

I'm trying to install Elasticsearch on my windows 10 virtual machine. I installed JDK, and already set the environment path. I downloaded the Elasticsearch and run the cli commands for installation as given in the guide. It prompted this error messages:

Error: Could not find or load main class org.Elasticsearch.common.settings.KeyStoreCli  
Caused by: java.lang.NoClassDefFoundError: org/Elasticsearch/cli/LoggingAwareMultiComman

Can someone help me out here?
