Loo. If you go into MAX and look under the software tab, does NI-IMAQ 2.51 show up? If so, make sure the Image Acquisition VIs are available in LabVIEW (or make sure the library files are available in your programming environment). If the VIs don't appear, or if the software isn't in MAX, then you probably have a dirty installation. To clean it up, make sure NI-IMAQ is totally uninstalled and that the NI-IMAQ folder is empty.
If everything appears to be normal in software, but the 1428 card still doesn't install, then the card may be bad. The best way to test this is to install the board on another computer. If it works on one computer but not the other, then it's definately a software problem.
