Hi tommpogg,
You are right, the lastest version of 5640R driver is 1.7.
Although there is no driver version for 2014, you could try the following workaround:
Can I Access My FPGA Target From LabVIEW 2013 64-bit?

I know this KB is talking about LV 2013 64b but the procedure is the same:
Using LabVIEW 2013 to build the project and create the bitfile for your application, then try moving over to LV 2014 to run the host application calling that bitfile.
I am pretty sure this workoraund is the only way to solve the problem.
Best,
