Hi Kalidas,
do you have NI-IMAQ installed on your computer, by any chance? I know that some versions of NI-IMAQ would give this error message and uninstalling NI-IMAQ and then reinstalling LabVIEW and NI-IMAQ after that would fix the problem.
If you’re seeing any other error messages, especially ones that refer to DLLs, let me know and that may be an indication of another problem.
Thanks!
