Hello, Yes I explained in my later post that the claim is true, because it is possible to use the feed with 64-bit applications (providing that you use sockets only and thanks to removed dependency with IQ32.DLL - in the past it was required to start the feed using 32-bit DLL, but now the same can be achieved without using this 32-bit DLL)
