"If you want to distribute an application developed with IMAQ Vision, install nivissvc.dll and nivision.dll in the system directory of every target machine. These DLL files were installed in your system directory when you installed IMAQ Vision. Copy the DLL files from your system directory to the system directories of the target machines or to an installation CD.
(!) Before distributing an application developed with IMAQ Vision, you must have an IMAQ Vision run-time license for each target machine. Contact National Instruments at 512 794 0100 to purchase run-time licenses."
