How do I build a 64 bit Windows application using NI-DAQmx in Visual Studio 2010

Hi,

How do I build a 64 bit Windows application using NI-DAQmx in Visual Studio 2010?

I'm trying to port a 32 bit application to 64 bit.  In visual Studio I added the 64 bit configuration to the project.  It compiled the source fine but reports link errors:

error LNK2019: unresolved external symbol DAQmxReadAnalogF64 referenced in function NI6008_AnalogInput NI_6281\NI6281.obj
error LNK2019: unresolved external symbol DAQmxCreateAIVoltageChan referenced in function NI6008_AnalogInput NI_6281\NI6281.obj
error LNK2019: unresolved external symbol DAQmxReadDigitalLines referenced in function NI6008_DigitalInput NI_6281\NI6281.obj

error LNK2019: unresolved external symbol DAQmxWriteDigitalLines referenced in function NI6008_DigitalOutput NI_6281\NI6281.obj
error LNK2019: unresolved external symbol DAQmxCreateDOChan referenced in function NI6008_DigitalOutput NI_6281\NI6281.obj

These, of course, are the NI functions I'm using.  The NIDAQmx.lib has been added to the Link Input property.

Any help would be appriciated.

Thanks,
