TibMsg is part of the 32bit Market Data interface, and it does not support 64bit. There is a reason that you can't find a 64-bit library. Only the new OMM Interface, which provides for 64bit.
There is an API that we are using from TIBMSG which is the TibMsg::ConvertToUTF8. So does it mean that there is no 64Bit counterpart for this? Is there a chance that this will be build in the 64 bit because this is the only DLL that is missing in the 64bit. Appreciate your reply.
The TibMsg library is part of the legacy interface, and it was designed to use with the RFA MD interface only, and as I said previously, we do not provide a 64-bit library for TibMsg and RFA MD interfaces.
If you double-check the 64-bit folder, you will see that it does not have RFA7_Connections_MDXXX.dll RFA7_SessionLayer_OMMXXX.dll that are the DLLs are the main library for the SSLED connection type, and support only 32 bit.
