Cosmos DB - Gateway Service has stopped

i'm working with Cosmos DB in windows server 2012 r2, but, when complete installation and initialize the service opens a popup showing that the gateway Service did not start, I looked in the forums and always fell into the same solution "lodctr / r" but nothing works

using the command prompt I attempted to start the gateway services manually and here is the results:

C:\Program Files\DocumentDB Emulator\Packages\GatewayService\GatewayService.Code>documentdb.gatewayservice.exe /?

Is the gateway service relevant? Any idea how to fix
