Solution

If this is your first time setting up this system, Error -50251 can indicate a corruption of the NI Device Driver installation. Try uninstalling and reinstalling the driver.
If it doesn't work, you can try to deactivate your anti-virus software and then try to install the driver. Sometimes, anti-virus software can block the good installation of a driver.
