Hello Mark, I am trying to install x-pack in windows and JVM details are as below 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) ---

Are you behind a corporate proxy? The error you are getting seems to be because your JVM cannot verify the SSL certificate of the elastic download site. That _shouldn't_ happen, but can sometime be caused by: - Weird JVMs, particularly OpenJDK builds that ship with a customised set of CA certs. - Corporate MITM proxies that generate their own SSL certificates on the fly. ---

The JVM was installed from the following site [http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html](http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html) Installing CA certificates from elastic site and adding them to local will help ? I have even tried to install it offline. But facing some FileNotFoundException.

Hey, can you try `file://C:...` to make sure you are using a proper URL, as Elasticsearch still tries to download the URL you specified and does not recognize it as a local file. --Alex ---
