I had installed lab view 8.6, and I have cDAQ 9172 for aquring data. My pc has 8.5 version already installed. Initially there was a driver problem and we reloaded latest driver NI-DAQ - 910I. System started aquring data but old VI used for aquring data did not work. At the same time when I tried to read examples it showed "Error 2 occurred at System Exec.vi. Command was ""C:\Program Files\National Instruments\Shared\example finder\1.0\bin\NIExampleFinder" -- labview 8.6 locale,en license,LabVIEWPro "can any body help me.
