ci_connect(): OCIEnvNlsCreate() failed

Question

I am using Laravel 5 with yajra/laravel-oci8 . Problem is that I am getting this error:

ErrorException in Oci8.php line 81:
oci_connect(): OCIEnvNlsCreate() failed. There is something wrong with your system - please check that PATH includes the directory with Oracle Instant Client libraries

I edited System Environment variables, activated OCI8 in php.ini and tried everything that I could find on Google but none of that worked...

EDIT: Added PHP Enviroments:

Does someone knows where's the problem?
