In some environments (it works in general case), where Runtime version is installed only, there are "SerializationException" errors during start of remote run or after it ends and tries to report result to Storage Server.

Installing .Net4.5.1 seems to fix the problem

System.Runtime.Serialization.SerializationException was unhandled
  Message=Type 'System.ServiceModel.Channels.ReceivedFault' in Assembly 'System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not marked as serializable.
