When I create an icon of an express VI on the Block Diagram, "error loading National Instruments\LabVIEW 2012\resource\lvanlys.dll" appears. And when I double click the icon, it is shown on the screen "unable to view properties". I cannot run the VI, and the errors listed are like "SubVI 'simulate signal': SubVI is not executable". I do not know how to solve this problem.
Hope someone can help me. Thanks a lot!
