Hi Team,

I am running EMA Consumer450 with single machine id successfully.
When I try to run more than one instance with the same machine id, I am getting below listed error. Is it possible to run multiple instances with single machine id?

Error Description:

    Hello @Maha Rana Parthap Sing,

    A single machine ID should only be used with a single instance of an application. If you need to run more than one app or multiple instances of an app, then please contact your Refinitiv account manager to get multiple machine ID's.
