connecting to iqan system with a cat comm adapter 3 for software update

We have a IQAN R7 software app on our computer.  We are trying to communicate with a IQAN software on a Weiler brand machine. It has a CAT ET port that we are supposed to connect to the machine with via a CAT Comm adapter 3.  When I go to connect, selecting CAN on the connection page, it gives a error code E126 Unable to load CA3rp32.dll. Please update RP1210 driver to a 64-bit version. I dont know that we have that option to do a RP1210 update.
