Does anything need to be added to a dll that is not required in an executable to create a DAQmx task successfully?

Does anything need to be added to a dll that is not required in an executable to create a DAQmx task successfully? I have no problem making an .exe that creates a DAQmx task but I get floating point errors in DAQmxCreateAIAccelChan when I attempt to do this in a dll. One example is in the following autogenerated code.

TaskHandle taskOut;

DAQmxErrChk(DAQmxCreateTask("DAQTaskInProject", &taskOut));
// floating point error occurs in the following call
DAQmxErrChk(DAQmxCreateAIAccelChan (taskOut, "Dev1/ai0",
"Acceleration", DAQmx_Val_PseudoDiff, -5, 5, DAQmx_Val_AccelUnit_g,
1000, DAQmx_Val_mVoltsPerG, DAQmx_Val_Internal, 0.001,
""));

DAQmxErrChk(DAQmxCfgSampClkTiming(taskOut, "",
1000, DAQmx_Val_Rising,
DAQmx_Val_FiniteSamps, 100));

*taskOut0 = taskOut;

Error:
return DAQmxError;
}
