    From my checking, I assume that you are using EMA 3.5.0.L1 in Real-Time SDK C/CPP 1.5.0.L1.

    It looks like to be a bug fixed in EMA C++ 3.5.1.L1 in RTSDK C++/C Release 1.5.1.L1.

    - [ESDK-4086] - EMA must check both DictionaryUsed and DictionaryProvided to download dictionary from network

    The workaround for EMA 3.5.0.L1 is loading the dictionary from the local files by using Dictionary_2 in Consumer_3. 

        <Consumer>
          <Name value="Consumer_3"/>

          <!-- ChannelSet specifies an ordered list of Channels to which OmmConsumer will attempt to    -->
          <!-- connect, one at a time, if the previous one fails to connect                            -->
          <ChannelSet value="Channel_3"/>

          <Logger value="Logger_1"/>
          <Dictionary value="Dictionary_2"/>
          <XmlTraceToStdout value="0"/>
        </Consumer>


            <Dictionary>
                <Name value="Dictionary_2"/>
                <DictionaryType value="DictionaryType::FileDictionary"/>

                <!-- dictionary names are optional: defaulted to RDMFieldDictionary and enumtype.def -->
                <RdmFieldDictionaryFileName value="./RDMFieldDictionary"/>
                <EnumTypeDefFileName value="./enumtype.def"/>
            </Dictionary>

    Then, copy the RDMFieldDictionary and enumtype.def files from the Cpp-C\etc to the working directory of the application.

    Otherwise, you can upgrade to the latest version of the Refinitiv Real-Time SDK.
