Do you mean you want to show the about window when someone presses a button?
The about window isn't a VI. At least not a traditional VI, it's probably a FP resource without a diagram.
Do you just want to show it as is? Or do you need to add functionality?
You can show the about window (by invoking the menu item "APP_ABOUT").
If you need to customize the behavior, you 'd need to take a screenshot, and make a new VI and paste that screenshot. Perhaps edit the image in paint or something, and add controls and indicators to add the dynamic elements.
