NI Vision Acquisition Software (VAS) is the NI driver software used for acquiring, displaying, logging, and monitoring images from a wide range of different camera types. Installing these drivers results in added function palettes in the LabVIEW development environment corresponding to each subset of the driver API.
If you are using Vision Acquisition Software August 2015 and do not activate that software at the time of install or during the trial period, you will not be prompted to activate if you attempt to use the NI-IMAQdx VIs later on. The NI-IMAQdx VIs will not appear on the palette and VIs using these functions will be broken. To fix this, activate the software in NI License Manager.Note 2:
The NI-IMAQ driver (used for NI Camera Link frame grabbers only) does not require activation.
