Hi, I am struggling to restart elastic search. It gives following error -  
java.io.IOException:  
failed to write in data directory [C:\ELKSetup\elasticsearch\data\SAXOVMS2272\nodes\0\indices\va1RG-sVS96HvYR-SjmZMQ\3] write permission is required

Few days back server on which we have elasticsearch running was restarted, before that it was working fine.But after restart server, elasticsearch service is down and when I restart service it give me error-

java.io.IOException:  
failed to write in data directory [C:\ELKSetup\elasticsearch\data\SAXOVMS2272\nodes\0\indices\va1RG-sVS96HvYR-SjmZMQ\3] write permission is required
