Hello!
I have failed to find that version of dll on ni4882 drivers page. There are lot of drivers from major version 1 to 17 but no 8 at all. I try to use old dll that compiled with connection with NationalInstruments.NI4882.dll version 8.1.20.119 and i can't recompile it. So i need exactly 8.1.20.119 version dll.
