I have a couple of unmanaged C++ projects that I have been building with CVI in VS 2005. I just updated to the 8.3 NIDAQmx drivers, and when I attempted to build those projects, I got an error that the linker was unable to find "nidaqmx.lib". I solved the problem by finding the file on my disk, and adding the path "\Program Files\National Instruments\NI-DAQ\DAQmx ANSI C Dev\lib\msvc" to the additional libraries directory.
Seems like this should be covered in the release notes.
Best Regards,
Matthew
