lvdaq.dll

I have an old LabVIEW program from a previous research student that will open with the PCI-MIO-16E-4 DAQ card. It worked before on an older computer. Now we are trying to open the program on a Windows 7 64-bit computer but there is a loading error.
"C:\Program Files\National Instruments\Labview 7.1\vi.lib\DAQ\vidaq.dll ". I do not know where to access this.

LabVIEW 7 (and probably 7.1) used a version of DAQ now called "Traditional DAQ", which was shortly (Version 8?) replaced by NI-DAQmx, a tremendous improvement in usability, flexibility, and overall-ability.  My suspicion is the "missing file" is part of the largely-abandoned "Traditional DAQ" part of LabVIEW.

However, it appears that your device might also have a DAQmx driver.  What you would need to do is to open the old LabVIEW code and replace the DAQ sections that use Traditional DAQ with new code that uses DAQmx.  You will probably find (as I did) that ripping out the Traditional DAQ code (which can be very complicated to configure and to figure out) with DAQmx code that does the same thing in 3-4 functions, much easier to understand and to configure.
