Can you share ther permissions of that file on your system?
Also what operating system are you trying to install Elasticsearch on?

Hello. I changed the permissions of all the files that it wan't able to access. It then started running but then within a few seconds stopped and the message displayed was:
```
ERROR: [2] bootstrap checks failed
[1]: max number of threads [1024] for user [elasticsearch] is too low, increase to at least [4096]
[2]: system call filters failed to install; check the logs and fix your configuration or disable
system call filters at your own risk
```
My OS is RHEL6

I'm not expert on those settings but if you need more help, you need to explain what you did and what are the logs.
