Linux RHEL7.5 64 bit hmp application

Hello.
I am using Dialogic HMP for LInux 4.1 Update 236 and I have a 32 bits application using libraries (srl, dxxx, ipm, cnf, devmgmt) and it works just fine right now.
I need to port this application to RHEL 7.4 64 bits. I see no 64 bits version of these libraries exist at /usr/dialogic/lib64. Does this mean support for 64-bit is not available? 

Thanks in advance.
