Hi,

I downloaded the elasticsearch msi installer, service is installed but I am unable to start the service. I tried command line to start the service (.\elasticsearch.exe) it gives following error.

**Error occurred during initialization of VM**  
**Java HotSpot(TM) Client VM warning: Cannot open file logs/gc.log due to No such file or directory**

I tried to run the service directly from Service Manager and its throwing exception. Event viewer shows following error:

**Application: elasticsearch.exe Framework Version: v4.0.30319** Description: The process was terminated due to an unhandled exception. Exception Info: Elastic.ProcessHosts.Process.StartupException at Elastic.ProcessHosts.Process.ProcessBase.HandleException(System.Exception) at System.Reactive.ObserverBase`1[[System.__Canon, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]].OnError(System.Exception) at System.Reactive.Observer`1[[System.\_\_Canon, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]].OnError(System.Exception) at System.Reactive.Linq.ObservableImpl.AsObservable`1+_[[System.__Canon, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]].OnError(System.Exception) at System.Reactive.AutoDetachObserver`1[[System.\_\_Canon, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]].OnErrorCore(System.Exception) at System.Reactive.ObserverBase`1[[System.__Canon, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]].OnError(System.Exception) at Elastic.ProcessHosts.Process.ObservableProcess+<>c__DisplayClass22_0.<CreateProcessExitSubscription>b__0(System.Reactive.EventPattern`1\<System.Object\>) at System.Reactive.AnonymousSafeObserver`1[[System.\_\_Canon, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]].OnNext(System.\_\_Canon) at System.EventHandler.Invoke(System.Object, System.EventArgs) at System.Diagnostics.Process.OnExited() at System.Diagnostics.Process.RaiseOnExited() at System.Threading.ExecutionContext.RunInternal(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object, Boolean) at System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object, Boolean) at System.Threading.\_ThreadPoolWaitOrTimerCallback.PerformWaitOrTimerCallback(System.Object, Boolean).
