Hello,

We have seen issues like this in the past [Kibana 5 default password](https://discuss.elastic.co/t/kibana-5-default-password/55073) , [Install failure on windows - EPERM: operation not permitted](https://discuss.elastic.co/t/install-failure-on-windows-eperm-operation-not-permitted/66381/5) on windows where the AV had a lock on the file and that caused the installation to fail. Are you using an Antivirus on this system ?
