I can.
So question is: what did you do? What are the logs?

I'm new to this, so please bear with me.
Here is what i did:
1. I ran the "bin\elasticsearch.bat" in Command Prompt
2. I opened and typed: curl [http://localhost:9200/](http://localhost:9200/) which gave this output:
PS C:\Users\sbm\> curl [http://localhost:9200/](http://localhost:9200/)
curl : Unable to connect to the remote server
At line:1 char:1
- curl [http://localhost:9200/](http://localhost:9200/)
-
```auto
+ CategoryInfo : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-WebRequest], WebException
+ FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeWebRequestCommand
```
Do you know what I'm doing wrong?

Are there any more details from the PowerShell exception? As an exercise, do you get the same response using the `iwr` alias for `Invoke-WebRequest` as opposed to the `curl` alias?

No more details than that.
yes, then I get this:

Is there anything in the output where you have `elastisearch.bat` running?

I'm not sure? - the Command Promt is open and I have ran the elastisearch.bat

Elasticsearch will write out log messages to standard output by default when started with Elasticsearch.bat. Can you show the log messages written out?

I'm not sure how to find that - is that the text that shows up on the Command Prompt when in running the Elasticsearch.bat? In that case:

Yep, that's it. Here's the problem

It looks like you're running on 32-bit Windows. The log message indicates what you can do to disable X-pack Machine Learning but still use other features unsupported. The elasticsearch.yml file can be found in the config directory and you'll need to restart Elasticsearch for the change to take effect.
